Speech before words: why start at birth
Many parents quietly wonder, sometimes with a little embarrassment, if talking to a newborn really makes sense. They don't understand words, they don't respond, they sleep three-quarters of the time. And yet, research in developmental neuroscience is clear: the first weeks and months of life are a period of exceptional brain plasticity. What the child hears then literally shapes the architecture of their brain.
The work of Patricia Kuhl, a researcher at the University of Washington and specialist in child language development, has shown that an infant's brain is capable of processing sounds from all languages in the world until about six months of age. After that, it gradually specializes in the sounds of its native language. Every vocal exchange, every story read aloud, every daily comment contributes to this early and irreplaceable calibration.
What science says about the language bath
The concept of 'language bath' refers to a child's continuous and natural exposure to human speech from their first days. It's not about structured learning sessions, but rather ordinary, lively speech, addressed directly to the child in the course of everyday life.
A longitudinal study conducted by researchers Hart and Risley, published as early as 1995, established a statistically significant link between the number of words heard in the early years and subsequent language abilities. Their data suggest that a gap of several million words can develop between children by the age of three, depending on the richness of verbal exchanges in their family environment.
More recently, fMRI (functional magnetic resonance imaging) studies have confirmed that the brain regions related to language activate in infants when exposed to human speech—and this, long before they are able to produce any words.
Child-directed language: a natural and instinctive form
'Baby talk' has a real function
Sometimes called 'motherese' or 'parentese,' this is the spontaneous way adults modulate their voice when speaking to a toddler: higher pitch, slower rhythm, exaggerated intonations, frequent repetitions. Far from being anecdotal, this instinctive vocal adaptation serves a precise function. It attracts and maintains the infant's attention, marks the boundaries between words, and facilitates the segmentation of the sound stream.
The Haute Autorité de Santé (HAS) and early childhood professionals recommend that parents should not hesitate to speak naturally and warmly with their child, without trying to artificially correct or simplify their way of speaking. The authenticity of the bond takes precedence over linguistic 'performance.'
The importance of gaze and turn-taking
Talking to a baby isn't just about making sounds. It's about engaging in a true communication protocol that includes gaze, pause, and waiting for a reaction—even a tiny one. What's called 'turn-taking' establishes itself very early: the parent speaks, the baby responds with a coo, a movement, a facial expression; the parent continues. This alternation, even if asymmetrical, is the foundation of dialogue and relationship.
Research in developmental psychology, particularly that from the Geneva School, heir to Piaget, emphasizes that the child is not a passive recipient of language. They are an active participant in communication from the first days, and their responses—however subtle—deserve to be interpreted as such.
Integrating speech into daily routines
No need for educational programs or dedicated time. Opportunities to talk to your child are numerous every day, provided you recognize and simply seize them.
During personal care
Diaper changes, baths, and dressing are moments of intense physical contact that naturally lend themselves to verbal exchange. Naming body parts, describing what you're doing ("I'm putting on your soft onesie"), anticipating aloud ("we're going to wash your hair now"): these little daily narratives create a reassuring framework and enrich vocabulary in a concrete and embodied way.
During meals and carrying moments
Breastfeeding or bottle-feeding, each feeding is an opportunity for closeness and speech. Babywearing also frees up hands and encourages face-to-face exchanges. Talking to your child during these moments isn't artificial: it's a natural extension of the bond you're creating.
Reading aloud from the first weeks
Reading aloud to a newborn might seem premature. However, it is one of the most recommended practices by speech therapists and pediatricians. Board books, nursery rhymes, lullabies: all these sound forms enrich the child's linguistic environment and create powerful emotional rituals. The association between shared pleasure and speech is itself foundational to the future relationship with reading.
Multiple languages: should we worry about early bilingualism?
Many families in France live with two or more languages. The question of early bilingualism often comes with an underlying concern: won't speaking several languages to a baby confuse them or delay their development?
The specialists' answer is unambiguous: no. Children exposed to multiple languages from birth develop linguistic skills just as solid as monolingual children, with the added benefit of documented cognitive flexibility. What is sometimes called a slight 'delay' in the appearance of the first words is statistically insignificant and resolves naturally.
The Académie Française itself, in a joint publication with learned pediatric societies, has recognized the benefits of early bilingualism when experienced naturally and affectionately, without pressure or hierarchy between languages.
When to worry and whom to consult
Language development follows general stages, but each child progresses at their own pace. As an indication, and according to the benchmarks established by the French Society of Pediatrics, a child generally produces their first recognizable words around 12 months, and begins to put two words together around 18 to 24 months. But these benchmarks are averages, not absolute norms.
If you observe a total absence of babbling around 9 months, an absence of reaction to familiar voices, or a regression in acquired language skills at any age, it is relevant to discuss it with your pediatrician or treating physician. A speech therapy assessment can be prescribed from a very young age, and early intervention, if necessary, is always more effective than late intervention.

Speech as care: a philosophy for everyday life
In an era saturated with visual stimuli and screens, human speech—live, embodied, addressed—remains the most precious and inexpensive developmental tool one can offer a child. It requires neither technology nor material investment. It only requires presence, attention, and the conviction that this little being, though silent, hears you and responds in their own way.
This is exactly what slow parenting advocates: slowing down enough to name things, tell stories about the world, sing a lullaby without looking at your phone. These seemingly ordinary moments are, for a child's brain, foundational.
If you set up a floor play space to encourage these face-to-face exchanges, the Treelys play mat is designed to support these moments of closeness and sensory exploration in the first months. It offers a soft and secure setting for tummy time, precisely those moments where speech, gaze, and contact naturally come together.
