Month eight: a new guide

Last reviewed · 4 min read · 13 sources · Plain-text version

The 7-to-12-month guide takes over today. The 9-month list is the frame for the weeks ahead, read as 'most babies by 9 months,' and crawling isn't on it.

Seven months are done; the notes for them are at the seventh month. From today these notes draw on the 7-to-12-month guide, and the first thing to take from it is a list you'll read as a horizon, not a test.

Heart

By 9 months, most babies are shy, clingy, or fearful around strangers; show several facial expressions, like happy, sad, angry, and surprised; look when you call their name; react when you leave; smile or laugh at peekaboo; make lots of different sounds like "mamamama" and "bababababa"; lift their arms to be picked up; look for objects dropped out of sight; bang two things together; get to a sitting position on their own; sit without support; move things from one hand to the other; and rake food toward themselves with their fingers (CDC). Your baby is 7 months old. Some are here already; the rest have two months to arrive, and "most" means at least 75% of babies by that age, so a missed one is a reason to check in, not to wait (Zubler et al., 2022). Born early? Use corrected age for milestones during the first 2 years (AAP).

Head

Notice what isn't on it. Crawling isn't on any CDC checklist (Kretch et al., 2022). Taking a few steps alone and pointing to ask for things are 15-month milestones (CDC), and pulling up to stand and walking while holding on to furniture are 12-month ones (CDC). The month ahead isn't a race across the floor; this month's list is sitting, hands, sounds, and faces.

Body

What the month looks like, from the guide. Crawling is usually mastered between 7 and 10 months by the babies who crawl, though a few scoot on their bottoms or slither instead (AAP). Early in this stage, your baby rakes things in with the whole hand (AAP). Wariness of strangers, often one of the first emotional milestones, isn't caused by spoiling (AAP). Each gets its own day this month.

Try today

  1. The mother reading a printed list aloud with a pencil in hand while the father, cross-legged on the rug, steadies the baby, who is reaching for the paper.

    The nine-month frame

    Time: 5 minutes, after a feed

    1. Read the 9-month list out loud, slowly, with your partner if you can (CDC).

    2. Next to each item your baby has already done once in front of you, make a small mark. Once is enough, and no claims about the rest.

    3. Leave the unmarked ones alone. They have until 9 months, and "most babies" means at least 75% by then (Zubler et al., 2022).

    4. Put the list where you'll see it. You'll mark it again at the end of the month.

    Make it work:

    If you were told to use corrected age, use it here too (AAP).

Watch for

  • Normal

    a baby who still sits only propped, or with hands down; sitting without support has until 9 months (CDC).

    Talk with your pediatrician

    if your baby can't sit with help, or seems very stiff or very floppy (AAP).

  • Normal

    "bababa" with no "mama" yet; lots of different sounds is a 9-month skill (CDC).

    Talk with your pediatrician

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

  • Normal

    reaching with both hands and rolling both ways.

    Bring it up

    if your baby uses one arm or leg much more than the other (AAP) or has lost skills they used to have (CDC).

  • Normal

    a fever that came and went with a cold.

    Call within 24 hours

    if a fever lasts more than 3 days, or comes back after a day without one (AAP).

For you

The mother alone at the kitchen counter afterward, phone face-down, writing two lines on the back of the list, the father visible through the doorway holding the baby.

A new month, the same list for you, briefly. The CDC's urgent maternal warning signs still apply, and they apply for a full year after birth: a headache that won't go away or gets worse, dizziness or fainting, changes in vision, a fever of 100.4°F or higher, extreme swelling of the hands or face, trouble breathing, chest pain or a fast-beating heart, severe belly pain that doesn't go away, heavy bleeding, overwhelming tiredness, or thoughts about harming yourself or your baby. Any of them means care now, and tell whoever sees you that you were pregnant within the last year (CDC).

If you're the partner: the baby's list went on the fridge today. Hers goes in your phone, where you'll actually see it.
