Your voice

Last reviewed · 3 min read · 16 sources · Plain-text version

Your baby has known your voice since before birth. Today is about using it: parentese, reading aloud, and saying the hard things out loud too.

A mother on a sofa holds her awake newborn up near her face in afternoon window light, mouth open mid-word, the baby gazing back at her.

Eleven days in: feed, change, sleep, repeat. Today's note is about the one tool you carry everywhere and never have to charge: your voice.

Heart

Your voice was the first familiar thing. In a tiny, influential study, ten newborns under 3 days old learned to suck in a rhythm that played their own mother, rather than another woman, reading Dr. Seuss; the authors suggested hearing her before birth may play a role (DeCasper & Fifer, 1980). Babies can recognize a parent's voice within the first month (AAP), so every narrated feed adds to that.

When you answer a coo or a cry with words, that's serve and return, the back-and-forth that helps build neural connections (Harvard Center on the Developing Child).

Head

That sing-song voice you slip into has a name: parentese. In a small lab study, 16 babies just 2 days old preferred infant-directed speech to adult-style speech (Cooper & Aslin, 1990), and the AAP notes that babies like high-pitched voices in general (AAP). The outcome research is with older babies: in a randomized trial, coaching parents on parentese and back-and-forth talk at 6 and 10 months led to more babbling and more words at 14 months (Ferjan Ramírez et al., 2019). For a newborn, the benefit is inferred.

The AAP also recommends shared reading beginning at birth, based on research with young children (Klass et al., 2024).

Body

Sometime in the next few weeks you may notice your baby go quiet, or look or turn, when you speak; the AAP lists looking or turning toward familiar sounds and voices as something a 1-month-old may do (AAP). If it hasn't happened yet, nothing is wrong.

Try today

  1. On a sofa in afternoon window light a mother holds her eleven-day-old about ten inches from her face, eyebrows up and eyes wide mid-word, the baby staring back at her mouth.

    Talk in parentese

    Time: A few minutes, whenever your baby is alert · Talk in parentese in the guide

    1. Get face to face, about 8 to 12 inches away, where your baby sees best (AAP).

    2. Raise your pitch, slow down, and stretch out your words: "Hiii, sweeet baaaby" (AAP).

    3. Widen your eyes and smile as you talk.

    4. Pause to give your baby a turn, then respond to whatever they do.

    Make it work:

    Use real words, just warmer and slower. If your baby looks away or fusses, that's "done for now."

Watch for

  • Normal

    irregular breathing with short pauses, plus squeaks and sighs.

    Go to the ER now

    if breathing stays faster than 60 breaths a minute, pauses last longer than about 10 seconds, or the ribs pull in with each breath (AAP).

  • Normal

    8 to 12 feeds in 24 hours if breastfed (AAP).

    Call your pediatrician right away

    if your baby is feeding poorly, has a weak suck, or vomits more than once (Nationwide Children's).

  • Normal

    a run of short, close-together feeds in the evening, called cluster feeding.

    Call your pediatrician

    if your baby is more than a week old and feeding constantly, or if you're worried about latch or milk supply (Cleveland Clinic).

For you

At the kitchen table in late afternoon light the mother talks with her eyes down and her hands around a mug while her partner sits close, turned toward her and listening, saying nothing.

Your voice has one more job today: saying the hard thoughts out loud. "I don't feel like myself." "I'm scared I'm doing this wrong." Said out loud to someone, they get smaller.

The AAP says 50% to 80% of people who give birth get the "baby blues," mild, short-lived mood changes in the first 2 weeks (AAP). Feelings that are severe, or that last longer than 2 weeks, may be postpartum depression, which can be treated (NIMH). You don't have to wait for a visit: call or text the National Maternal Mental Health Hotline at 1-833-TLC-MAMA (1-833-852-6262), or call or text 988. In an emergency, call 911 (CDC). Thoughts about harming yourself or your baby mean get care right away (CDC).

If you're the partner: ask how she's really doing, then stop talking and listen.
