Eight months. The 9-month list as a celebration, not a test; the sitting, scooting, or crawling video with no claims attached; the hotlines once more, lightly; and where the notes go next.

An East Asian father crouched with his phone held low, filming his thirty-four-week-old scooting on their bottom across a living-room rug toward the mother, who sits on the floor with open arms.

Eight months. Here is the list once more, for celebrating rather than scoring, and then where the notes go next.

Heart

By 9 months, most babies are shy, clingy, or fearful around strangers; show several facial expressions; look when you call their name; react when you leave; smile or laugh at peekaboo; make lots of different sounds like "mamamama"; lift their arms to be picked up; look for things dropped out of sight; bang two things together; get into a sit and sit without support; move things from hand to hand; and rake food toward themselves (CDC). Your baby is eight months, and that list is for a month from now, set at skills at least 75% of babies show by then (Zubler et al., 2022). Read it for the ones you've already seen, and smile at them.

Head

What you did this month, in the research's terms: you answered babble right away, which is what reshaped the sounds of 9.5-month-olds in the lab (Goldstein & Schwade, 2008); you kept offering the foods that got refused, because it can take 8 to 10 or more tastes (Spill et al., 2019); you said a quick, cheerful goodbye instead of sneaking out (CDC); and you anchored the furniture (CPSC). None of it needed equipment.

Body

The ninth month is the moving month. Pulling up to stand and walking while holding on to furniture are the 12-month milestones ahead (CDC), and pulling up often arrives before a baby knows how to get back down (AAP). So the mattress goes to its lowest setting before they can stand (AAP), and the walker stays in the store; they don't help and they send thousands of children to hospitals each year (AAP). The 9-month visit, with its screening questionnaire, is next month too.

Try today

  1. The baby sitting alone on the rug with a soft ball in both hands, looking straight into the father's phone propped against a book on the floor, the mother's knee just in frame beside the baby.

    The sitting-alone video

    Time: 2 minutes, baby rested, floor cleared

    1. Prop the phone against a book on the rug and sit the baby in front of it with a favorite toy, you right beside them.

    2. Say the date and "eight months" out loud at the start, and nothing else about what they can or can't do.

    3. Record a minute: a sit, a reach, a scoot or a crawl if there is one, a topple caught in your hands.

    4. Send it to the person who hasn't seen them since the seven-month one; the video call with family is the AAP's one screen exception (Hill, AAP).

    Make it work:

    If the baby scoots instead of crawling, film the scoot. Crawling isn't on any checklist (Kretch et al., 2022), and 4.3% of healthy babies never do it on hands and knees (WHO Multicentre Growth Reference Study Group, 2006).

Watch for

  • Normal

    a baby who cries when you leave the room and stops within minutes of your going; that's attachment, not spoiling (AAP).

    Bring it up with your pediatrician

    if by 9 months your baby doesn't sit without support, look when called, or babble lots of different sounds (CDC).

  • Normal

    a first fever during a cold, under 104°F, in a baby who still drinks and plays.

    Call 911

    if your baby has a seizure that lasts more than 5 minutes, and get them seen right away even after a short one (AAP; AAP).

  • Normal

    knowing this baby better than anyone alive.

    Call anyway

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

For you

The mother and father side by side on the sofa after dark, the baby asleep in the father's arms, the mother showing him something on her phone with the kitchen light the only light on.

Eight months of you. 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). Partners too: about 10% of fathers have depression around a birth, with higher rates reported at 3 to 6 months after (Paulson & Bazemore, 2010), which is now. Ask each other the real question tonight, and listen to the answer.

If you're the partner: say the thing she did this month that you'll remember. Then keep reading together: the 7-to-12-month guide has the whole stretch to the first birthday, and the notes continue tomorrow at your ninth month.
