First bites, first allergens, maybe a first tooth, and a sit that holds. What seven months changed, what the 9-month visit will ask, and where these notes go next.

A South Asian family at a kitchen table in evening light, the thirty-week-old upright and buckled in a high chair, puree on their chin, the mother holding a spoon, father and grandmother laughing.

Two hundred and ten days. This month changed the most: food went in, allergens went in, a tooth may have come through, and the baby who flopped onto their hands in week 25 can sit through a meal.

Heart

Read the 6-month list as a description, not a test. By about now, most babies know familiar people, laugh, take turns making sounds, blow raspberries, reach to grab a toy they want, close their lips to say "no more," roll from tummy to back, push up on straight arms, and lean on their hands to sit (CDC). Many now sit upright without leaning once set up, which the AAP puts at 6 to 8 months (AAP). Born early? Count from corrected age, as you have all along (AAP).

Head

The next fixed point is the 9-month visit. The AAP recommends a standardized developmental screening there (Lipkin & Macias, 2020; AAP, 2025), often a parent questionnaire like the Ages & Stages Questionnaires (ASQ), plus an exam, questions about sleep and pulling to stand, and fluoride varnish once teeth are in (AAP). The road ahead, from the 9-month list: sitting without support, looking when you call their name, lots of different sounds like "mamamama" and "bababababa," and shyness with strangers (CDC). The 7-to-12-month guide has the visit in full.

Body

From tomorrow, that guide is the source these notes draw on: crawling, the pincer grasp, first words, family food. The table doesn't change. Breast milk or formula is still the most important source of nutrition (CDC); meals happen upright and buckled in the high chair (AAP), with an adult watching the whole time (CDC); and peanut and egg stay in the rotation, never as whole nuts (AAP).

Try today

  1. A phone propped against a fruit bowl, recording, as the mother offers a half spoonful of puree to the buckled baby, who leans forward open-mouthed; the father watches the baby, not the screen.

    The first-bite video

    Time: 2 minutes, at a meal your baby already likes · First tastes from a spoon in the guide

    1. High chair, harness buckled, baby upright (AAP). Prop the phone against something so both of your hands are free.

    2. Start recording, then offer half a spoonful of a puree your baby already eats, and wait for the open mouth (AAP).

    3. Narrate as usual: "Here comes the sweet potato. Mmm."

    4. Stop when they turn away or close their lips (AAP). Thirty seconds is plenty.

    5. Save it beside the day-one photo and the sitting-up video.

    Make it work:

    Your eyes stay on the baby, not the screen; watch at all times while they eat (CDC). A prop, not a hand, holds the phone.

Watch for

  • Normal

    a sit that holds for a whole meal and a roll both ways on the floor afterward (AAP).

    Talk with your pediatrician

    if your baby can't sit with help, doesn't roll in either direction, or doesn't bear some weight on their legs by 7 months (AAP).

  • Normal

    a face at a new food, then three more bites; it can take 10 to 15 tries (AAP).

    Call 911

    if your baby ever has trouble breathing, swelling of the lips, face, or tongue, widespread hives, or sudden floppiness after a food (NIAID).

  • Normal

    "bababa" with no "mama" yet; repeated syllables are a 9-month skill (CDC).

    Talk with your pediatrician

    if your baby doesn't babble or imitate any sounds by 7 months (AAP).

  • Normal

    knowing this baby better than anyone alive.

    Call anyway

    if your baby just doesn't seem right to you. Trust your instincts; seven months have built them (Lurie Children's).

For you

The mother alone on the back step at dusk with a mug, phone face down beside her, looking at the garden; in the lit kitchen window behind her the father wipes the high chair tray.

Seven months done. The 6-month visit was the last of the four checkups at which the AAP recommends screening the birthing parent for postpartum depression (Earls et al., 2019), so from here the watching is yours, and the partner's: about 10% of fathers have depression around a birth, with higher rates, 25.6%, reported at 3 to 6 months after (Paulson & Bazemore, 2010). Once more, lightly: the National Maternal Mental Health Hotline is 1-833-TLC-MAMA (1-833-852-6262), call or text; 988 is for anyone; in an emergency, 911 (CDC). Ask each other.

If you're the partner: name the thing she did this month that you'll remember. Then read what's next together: the 7-to-12-month guide, and the notes continue tomorrow at your eighth month.
