Babies develop in an environment of relationships, and the parent-child relationship most strongly affects emotional and behavioural functioning ^[1][2]. “Serve-and-return” interactions—such as responding with a smile and encouraging words when babies babble—are foundational for early relationships ^[3] and happen through close attention to babies’ cues and by speaking, singing, and reading with children from birth. These same interactions help foster emergent literacy skills, which are language-based, socially acquired, and involve cognitive and socio-emotional domains of learning that are crucial for healthy child development.

Literacy is more strongly correlated with life-long health trajectories than either occupation or income ^[6]-[8], making it a practical focus for anticipatory guidance. The goal of promoting literacy in health care settings is not just to support school success or fluency in a particular language. The benefits of promoting early literacy in health settings through programs such as Reach Out and Read (ROR, United States) have been firmly established in the literature ^[9], which shows that:

• Parents follow the advice of health care providers when they promote early literacy.
• Health-based interventions can raise awareness, improve family literacy practices, and increase vocabulary in preschoolers—a particularly strong predictor of later school success ^[9]-[13].
• Parents referred by a paediatric care provider to their local library for support and education engage in richer, more frequent literacy practices with their infants and toddlers ^[14][15].

The human and economic costs of insufficient language exposure with a caring adult in the early years are significant. Low literacy is associated with chronic illness, low physical and mental health status, and high rates of acute health service use ^[8]. A recent estimate suggests that a 1% increase in adult literacy levels could boost Canada’s GDP by about $67 billion ^[16].

This statement focuses on the benefits of reading, speaking, and singing with infants and toddlers, with particular focus on family, relational, and social-emotional health. When “parent” (singular or plural) is used, it includes any primary caregiver and every configuration of family. “Family” refers to a child’s own household. Most literacy research has focused on mothers as the first and most consistent influence on children’s language and early literacy skills. However, a growing literature shows that involved fathers can positively influence school success and social-emotional well-being, regardless of income, ethnicity, or parental education level ^[17]-[21].

The role of early or emergent literacy

Early (or emergent) literacy (Text box 1) has been defined as “the skills, understandings, and attitudes that young children demonstrate before they are able to control conventional forms of reading and writing” ^[22]. Children living in culturally and language-rich environments develop important pre-literacy skills in their first 3 years of life that prepare them for learning to read, write, and succeed in school. These building blocks are best learned by direct experience, through face-to-face interactions with parents and caregivers, in language-rich, caring, engaging environments, and starting at home ^[14][23][24].

Specific emergent literacy skills, such as knowing the alphabet or printing one’s name, predict later literacy, even after controlling for IQ or socioeconomic status (SES). Historically, these are taught when children are very young ^[22]. The practice of storytelling at home is increasingly recognized as a strong predictor of literacy, particularly for cultures with oral traditions ^[25][26]. Children under the age of 4 who hear and tell stories at home are the most likely to have ease and interest in learning to read when they get to school ^[27][28].

There is a direct relationship between reading aloud to young children and school-readiness ^[12][13]. Both brain science ^[23] and research on programs such as Reach Out and Read ^[10][11] increasingly support reading aloud to infants from birth ^[15][29] to support attachment as well as emergent literacy. Child literacy depends on speaking and listening skills, and involves a wide array of understandings and competencies that lead to reading and writing ^[30].

Infant development and early language learning

Language plays a pivotal role in literacy development, and infants learn about language long before they first speak. Live, social interactions are critical to this process. Interacting one-on-one, using infant-directed speech (sometimes called “parentese”)—which involves a higher tone of voice, exaggerated pitch contour, and a singsong quality ^[31] —heightens infant attention and reinforces the connection between words and what they represent in real life ^[32][33].

By 4 months of age, infants can distinguish their own native language(s) from rhythmically similar ones ^[34]. At 6 months, infants are connecting the concrete nouns they hear with objects encountered or experienced in the home environment ^[32]. An infant’s language environment in the first 6 to 12 months is critical for developing the complex form and structure (syntax) of language (e.g., “Wh—” question words, demonstratives, particles) ^[34]. By 11 to 12 months, and provided sufficient language exposure ^[34], infants have a robust understanding for common words and native sounds in the language(s) spoken at home ^[31][32].

From age 12 to 20 months, children’s understanding of language meaning increases ^[32]. Receptive language (what babies understand) generally precedes expressive language (what babies can say). Finally, after studying the sounds and words around them for nearly 2 years, children will typically produce their first two-word utterances by their second birthday. There is typically a dramatic increase in language use at about this age ^[23].

Multiple language learning

Within hours of birth, newborns can distinguish their mother’s language, heard in utero, from a rhythmically unfamiliar one ^[31][34][35]. Infants are born with the ability to discriminate among many (likely all) of the phonetic units (sounds) of the world’s languages. By 4 months of age, however, babies pay attention only to the sounds of the language(s) they are hearing around them ^[34][36].

Between 6 and 12 months, the brain undergoes physical changes that reinforce neuronal connections supporting the languages an infant hears regularly and prune away the connections that have been rarely used. This selective neuronal commitment in one or more languages is important because it provides the foundation for many subsequent stages of language development, such as word learning and grammar. Infants exposed to two or more languages become native specialists for all the languages they are hearing ^[30][31], which benefits multiple language learning and important social competencies into preschool and beyond ^[6][37][38]. Milestones of language development are the same for children who learn more than one language.

Children exposed to more than one language may split their time and attention unequally between them and hear fewer words and sentences in each overall than monolingual peers. But when combined across languages, the size of their vocabulary is usually equal to or greater than that of children learning one language. Bilingual children, for example, tend to catch up to monolingual norms in elementary grades, especially when support for both languages is provided at home and in school ^[31]. A sound foundation in a first language creates optimal conditions for acquiring a second, because brain-based linguistic skills are transferrable ^[34][38].

The benefits of speaking and storytelling

Day-to-day experience with spoken words is critical because the more infants hear labels for what they are looking at and attending to, the stronger their overall comprehension becomes ^[32]. Until recently, it was believed that the number of words babies hear was key to growing expressive vocabulary ^[15][23]. However, research increasingly supports conversational turn-taking—especially between 18 and 24 months—as the more important mechanism for language learning ^[23]. Responsive back-and-forth (serve-and-return) interactions have been more highly correlated than word quantity with a wide range of later language and cognitive skills ^[23].

Personal storytelling—conversations with very young children about shared experiences—is a powerful driver of emergent literacy. Most children aged 24 to 30 months of age already know the rudiments of storytelling. They can, to varying degrees, sequence events, set an action in place and time, and organize a story around a central character (often themselves) ^[28]. Very young children first learn and explore the narrative form by talking about the past with their parents. In many cultures, parents speak with their babies frequently and in depth about shared past and future events. Developmentally, young children begin using narrative structure during play even before they can do it with words ^[28].

Toddlers learn about stories when a parent or other caring adult describes a shared experience ^[26][28]. They watch the narrator’s face, collaborate by nodding or repeating a word to show interest or to keep the teller engaged, and respond with emotion ^[28]. For cognitive and emotional reasons, children want to hear the same story over and over since repetition allows them to internalize the story and master its pieces. As families relate experiences together, they construct a shared narrative, strengthen family bonds, and teach what makes a good story ^[28][37].

Stories are also a passport into a child’s own or another culture ^[26][28][30]. Storytelling enlists all the social elements of language: Stories are told directly and expressively--often with vocal intonation, gestures, facial expressions, and body movement--and young listeners often better understand a story when it is told than when it is read ^[4][25].

The benefits of book sharing

While it is not yet clear whether shared reading from birth has direct developmental benefits ^[13], reading aloud together—early and often—appears to stimulate cognitive development more than other family activities. Shared reading is focused, immersive, and invites frequent, rich interactions and language exposures that positively predict language development ^[6][13].

Frequent mother-child book reading at home supports vocabulary and oral comprehension development in young children even when their home language is different from the one learned in school ^[39][40], and mothers tend to talk more with their children when reading than in other family contexts ^[14]. Book sharing with children at any age helps to instill love of reading ^[41].

By conversing with infants and toddlers while book sharing ^[6][14], parents can enrich learning by adding language-building strategies such as serve-and-return, dialogic reading (asking questions to encourage a child’s participation in story reading), and child-directed speech (e.g., exaggerating relevant phonetic differences). Research also suggests that quality parent-child exchanges during book sharing promote the emergence by school entry of cognitive skills that facilitate self-directed learning and successful interpersonal exchange ^[6][42].

Social-emotional benefits

Early, routine, quality book sharing has significant relational benefits for both infants and parents ^[14]. For infants, affect and shared reading have been linked to mother-child attachment security ^[15][41]. Frequent, quality book sharing appears to promote secure attachment, sustain infant attention, and enhance prosocial behaviours ^[17]. For parents, research has associated shared reading with improved parenting style ^[17], reduced maternal depression and stress levels ^[14][42][43], enhanced parental sense of competence and self-esteem ^[42][43], and improved parental responsiveness. Research is also showing how these relational factors are enhanced by behaviours associated with reading together, such as “snuggling up” (see Text box 2) ^[6][41][42].

Incorporating books into routines

There is strong evidence that early shared reading also reinforces positive family routines, with reading at bedtime ^[12] being a first, natural step ^[13]. Ideally, bedtime reading should begin from birth because of its positive effects for child sleep and child-mother relationships ^[13]. In one recent U.S. survey, bedtime reading was strongly associated with reading as a favourite family activity and with reading aloud 5 or more times per week ^[13][14]. Reading to infants from birth also provides bonding opportunities for siblings, non-breastfeeding parents, and fathers ^[13]. Multiple studies have associated early, routine, quality book sharing with maternal responsivity, school readiness, and positive cognitive outcomes ^[6].

Printed versus e-books: Is there a difference?

With even the youngest toddlers regularly encountering digital technologies in their everyday lives, parents may wonder how e-book sharing compares with printed books ^[41]. Although recent studies suggest that early learning is similar across the two media ^[49][50], evidence remains strong that even when parents are engaged and toddlers are attentive, sharing printed books teaches early literacy and language skills and promotes relational bonding better than e-books ^{[24][41][51][52]}:

• E-books and digital devices are not well designed for shared reading ^[41]. Children tend to hold or gaze at tablets in the ‘head-down’ position typical of solo use, and parents tend to ‘shoulder surf’ rather than tucking their child under an arm or curling up, as with paper books.
• Children cannot run a finger under a line of text ^[41] or bat at a picture without disrupting the page, and digital features such as page-turning, sound effects, and animation can be distracting ^[24]. Studies have shown that screen reading prompts more parent-child interactions about process and mechanics (e.g., page turns or screen touching) and fewer story-relevant comments ^[24][52].
• Children cannot practice book handling skills, such as pincer grasp for page turning or book orientation ^[52].
• When sharing a printed book, children need to decode what they are hearing and seeing, and develop their neural networks while doing so. E-books do much of this work for them, such that their brains are significantly less engaged ^[53].

The simpler the technology, the better it is for early brain development.

The benefits of singing

One recent US cohort study revealed that, in the newborn period, many families do not consider shared reading to be a "favourite" activity, but they do enjoy singing to their newborn ^[13]. Singing and speaking to babies both appear to increase infant attention via pitch contours, a consistent musical and linguistic structure, and tone ^[54]. Singing is akin to rhyming, and for infants, rhyme and rhythm may resonate even more than speech. While lullabies and children’s songs are often used to soothe or play, their simple, repetitive structure and sound may also promote early language development ^[54]. However, this powerful form of communication typically declines rapidly once children turn 2 ^[45].

An early, significant link between pitch and phonological awareness (the ability to recognize and work with sounds) reinforces the close links between music and literacy learning ^[45][55]. One study has suggested that rhythmical exercises and combining rhythm and song lyrics in children’s play help prepare the brain to learn to read and write ^[56].

Song, fingerplay (“Itsy-bitsy Spider”), and clapping games as literary practices can be incorporated into play, story times, and interactions with young children in ways that support diversity, creativity, and self-confidence ^[47][57]. Using song-based picture books to support and prolong singing/reading activities has been found to motivate and relax both parents and children, engage young children and siblings in synergistic learning, and enhance preschool oral language and vocabulary development, phonemic awareness, and phonological memory ^[45][46].

Communal musical activities (like a story time at the library or gathering to sing at an early years centre) encourage attentive listening and holding patterns in memory, both precursors to developing reading skills ^[46][47]. Children’s songs can teach language and basic spelling patterns, rhyming, sentence patterns and parts of speech, new vocabulary, and a sense of story and sequencing ^[47]. Using singing and movement together has helped teach pre-reading skills, such as letter sounds and medial phoneme skills (the middle sound of a word) and early word reading to kindergarteners ^[30][58]. Moreover, these skills are acquired in meaningful, active, and expressive contexts ^[48]. Music can be an entry point to a new language for children, who may be more socially comfortable singing along than speaking out ^[48]. Rather than getting stuck on words while reading, familiar melodies can help young children (or their parents) guess the right word, “go with the flow”, or “sing through” new vocabulary, experiences that help build confidence, phonological memory, and oral fluency ^[45].

Promoting literacy in health settings

Health care providers can promote and support early child literacy with every family they see in practice. A family-centred approach to literacy development means working with parents, building on each family’s strengths, and connecting with community resources like public libraries ^[37].

The Reach Out and Read (U.S.) program encourages clinicians to:

• Assess child and parent reactions and interactions around a book that is offered during the visit ^[9]. Giving young children a new book at every well-child visit can help providers watch for behaviours such as: ^[37]
  • The kinds of questions parents ask their children and the responses they accept or encourage.
  • Patterns of interaction between adults and children (e.g., whether children are encouraged to take the lead in conversations).
  • Accepted behavioural roles (e.g., associated with gender).
  • Customary style and manner of response (e.g., insistence on or avoidance of eye contact while speaking) ^[37].
• Bring a book in at the beginning of a visit to help with developmental surveillance and counselling ^[9][13][37]. Talking with parents about literacy-related routines and practices at home is a window on developmental milestones, family relational health and resources, and how best to help with advice, education, or referrals.
• Connect families with community ^[8]. Research shows that literacy promotion works best when it happens across more than one platform or context ^[14]. Libraries and community centres offer incentives and opportunities for parents to read more frequently, from a wider variety of books, and more interactively with children ^[14]. Many local library websites offer live-streamed reading events, virtual learning opportunities, and supportive resources. Families can typically get a library card even when they cannot provide proof of residency.

Clinicians can support the home cultures of their patients and families by being mindful of their own beliefs and biases, culturally aware, and welcoming diversity in the care setting ^[37][59]. See Text Box 3.

Recommendations

Talking to parents about the benefits of reading, speaking, and singing with their children from birth is something health care providers can do in virtually any context (e.g., at prenatal and well-child visits, during a hospitalization, or in a continuity clinic). The intervention can be brief yet meaningful, and expanded upon as the relationship with the family grows.

By providing information to families about brain development and serve-and-return interactions, clinicians can reinforce how everyday actions by parents can make lasting and positive differences for children and families:

1. Incorporate literacy promotion into everyday practice.

• Promote literacy with young families early, even before children are born, by helping them understand how language develops.
• Inquire regularly about stressors, schedules, or barriers that may interfere with one-on-one time with young children. This may include questions about digital media exposure, use, and access ^[24].
• Convey simply and clearly the nature and purposes of emergent literacy for ensuring a child’s optimal development ^[30], while respecting multiple forms of literacy and multiple pathways for promoting children’s literacy ^[30].
• Incorporate books into well-child visits whenever possible, and model how book sharing helps babies build relationships with both their parents and books.
• Link literacy milestones to other developmental milestones and anticipatory guidance (e.g., babies mouth their first books, use a pincer grasp to turn pages, and sit independently to hold a book).
• Create a language-rich environment in exam/waiting rooms and other health care spaces, using books, posters, or other tools that promote communication between parents and children.

2. Help families develop literacy-promoting habits.

• Assess parents’ own comfort level with reading aloud, and encourage those who lack confidence or skill to sing, talk, and tell stories with children.
• Encourage daily book sharing with all families, as a readily modifiable activity ^[12][14] that can lead into more interactive, responsive parent-child relationships, greater parental involvement in developing literacy skills, and healthier family routines (e.g., at bedtime).
• Encourage families to tell stories, speak, and sing in their home language.
• Connect families with community resources, such as local library programs, book-gifting programs, and early years centres, for literacy support and education.
