What a year changed

Last reviewed · 4 min read · 16 sources · Plain-text version

From a newborn to a baby who stands, points, pinches, waves, and pauses at "no": the year in one look, what the 1-year guide covers next, and a letter sealed for the second birthday.

A Latino grandfather on a sofa with twelve printed photos fanned across his lap, his fifty-two-week-old granddaughter standing at his knee pointing at the first, the mother writing at the table.

Two days from the birthday, the list of firsts is longer than any checklist. Today is the look back across the whole year, what the next guide covers, and a letter you won't read until this time next year.

Heart

The frame for the year that's ending: by 1 year, most babies play games like pat-a-cake, wave bye-bye, call a parent "mama," "dada," or another special name, understand "no," put something in a container, look for things they saw you hide, pull up to stand, cruise, drink from a cup you hold, and pick up small bits of food between thumb and pointer finger (CDC). Most, not all: the checklists hold skills at least 75% of children show by each age, so a missed one is a reason to check in, not to wait (Zubler et al., 2022). Born early? Corrected age counts for milestones through the first 2 years (AAP).

Head

What the 1-year guide covers next. Steps: most toddlers take a few on their own by 15 months and walk without holding on by 18, and not walking by 18 months is a reason to call, not to wait (CDC; CDC). Words: one or two besides "mama" and "dada" by 15 months, three or more by 18 (CDC; CDC). Tantrums, which happen most between ages 1 and 3 (Swanson, AAP). One nap: in a study of 172 children, two naps a day were well established by 9 to 12 months, and one afternoon nap by 15 to 24 (Weissbluth, 1995). And family jobs, like fetching shoes or carrying napkins to the table (CDC).

Body

The body's own story changes pace now. Most toddlers gain only 3 to 5 pounds during the whole second year, and by 2 their head is about 90% of its adult size (AAP). So appetite drops, often sharply, after the first birthday: one-year-olds need about 1,000 calories a day across three meals and two snacks, and their eating is erratic from day to day (AAP). The half-eaten dinners of the next few months are the first sign.

Try today

  1. Close on the mother's hand writing on lined paper beside the twelve photos laid out in a row, the first a newborn on a blanket, the last the same blanket with a standing baby, an envelope waiting.

    The year letter

    Time: 30 minutes, with the photos

    1. Lay the twelve monthly photos in a row, day one to the eleventh month, and write the firsts beside each in the order you remember them: the first smile, the first laugh, the first roll, the first bite, the first sit, the first stand, the first sound that meant something.

    2. Write what you'd tell the person in the first photo, the one holding a newborn: what turned out to be true, what turned out not to matter.

    3. Write what your baby does today, in plain words, with "should" left out. Three sentences is enough.

    4. Seal it, write the second birthday on the front, and put it with the photos. Nobody reads it for a year.

    Make it work:

    If your baby was born early, write both ages at the top; corrected age is the one that counts for milestones (AAP).

Watch for

  • Normal

    a baby who swings between fierce independence and clinging to you, especially when tired (AAP).

    Don't wait

    if your baby has lost words or skills they used to have; ask about screening, or call your state's early intervention program for a free evaluation without a referral (CDC).

  • Normal

    no steps alone yet; walking alone ran from 8.2 to 17.6 months in the WHO's study (WHO Multicentre Growth Reference Study Group, 2006).

    Ask about a developmental screening

    if your baby isn't pulling up to stand by 12 months (CDC).

  • Normal

    a dinner mostly dropped on the floor and a baby who's fine.

    Call your pediatrician right away

    if your baby looks or acts very sick, or you think they need to be seen urgently (AAP).

  • Normal

    a hairbrush used on the dog.

    Call 911

    if your baby is not moving, is very weak, or can't be woken (AAP).

For you

The mother alone at the coffee table at night, a second, shorter letter folded into its own envelope, writing a date one year ahead on the front, the grandfather's reading glasses beside her.

The letter to yourself, read next year. A second envelope, shorter: how you are, honestly, on this particular evening, and what you want to be different by the time you open it. Write the true version. If the true version includes sadness that has lasted more than two weeks, the Office on Women's Health's instruction is to go to the doctor now, not to wait for anything (Office on Women's Health); and the CDC's line for the whole year stands: if something just isn't right, or you aren't sure if it's serious, talk to your health care provider (CDC). The letter can wait a year. You shouldn't.

If you're the partner: write yours too, and seal it in the same envelope. About 10% of fathers have depression around a birth (Paulson & Bazemore, 2010); the honest version is the only one worth opening next year.
