# Day 212: Sitting, then getting there

> Sitting without support and getting into a sit alone are both 9-month skills, and healthy babies first sat alone anywhere from 3.8 to 9.2 months. The reach that builds balance, and the mattress.

This guide is general education that summarizes published research and guidance from groups like the American Academy of Pediatrics, the CDC, and the WHO. It isn’t medical advice, and every child develops on their own timeline. Your pediatrician knows your child; if something feels wrong, call them. In an emergency, call 911.

Somewhere around now the hands start to come up off the floor. Today is sitting: what's on the list, how wide the window is, and the one piece of furniture to change before it matters.

## Heart

Sitting comes in steps. First your baby "tripods," leaning forward on their arms. By 6 to 8 months, many can stay upright without leaning on their hands once you sit them up, though getting into a sit alone comes later ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-4-to-7-Months.aspx)). For many babies the tripod is behind them now, and the next two steps are both on CDC's 9-month list: sitting without support, and getting to a sitting position on their own ([CDC](https://www.cdc.gov/act-early/milestones/9-months.html)). Two different skills, and the second usually trails the first.

## Head

The window is wide. In a WHO study of 816 children in five countries, healthy babies first sat alone anywhere from 3.8 to 9.2 months ([WHO Multicentre Growth Reference Study Group, 2006](https://pubmed.ncbi.nlm.nih.gov/16817682/)). A 7-month-old who still tips sideways after a minute is inside that range, and so is the one who sat at 5 months. Held upright with their feet on the floor, many babies bounce around now, a warm-up for standing ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-4-to-7-Months.aspx)); that's a different skill again, and it isn't on this month's list.

## Body

The furniture. Set the crib mattress at its lowest position before your baby learns to stand, and keep cords well away from the crib ([AAP](https://www.healthychildren.org/English/safety-prevention/at-home/Pages/Make-Babys-Room-Safe.aspx)). A baby who can sit is a baby who will try to pull up, often before anyone sees it coming, so if the mattress is still high, tonight is the night. The crib stays bare: no pillows, blankets, bumpers, or stuffed toys ([Moon, AAP](https://www.healthychildren.org/English/ages-stages/baby/sleep/Pages/a-parents-guide-to-safe-sleep.aspx)). Sitting itself is learned on the floor. The WHO recommends interactive floor-based play several times a day ([WHO](https://www.who.int/news/item/24-04-2019-to-grow-up-healthy-children-need-to-sit-less-and-play-more)); a rug and a cleared floor are the whole kit.

## Try today

### The sit-and-reach

- **Time:** 3 to 5 minutes, a few times a day

1. Sit your baby on a rug with you kneeling behind them, your hands open at their hips. No cushion stack to fall off.
2. Put a toy on the floor just past their knees, a little to one side, so they have to lean to get it.
3. Let them reach, wobble, and recover. Catch the fall, not the wobble.
4. Switch sides, then once straight ahead.

**Make it work:** Leaning on a hand to get there counts. By 6 to 8 months many babies stay upright without their hands, and the list gives sitting without support until 9 months ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-4-to-7-Months.aspx); [CDC](https://www.cdc.gov/act-early/milestones/9-months.html)).

## Watch for

- **Normal:** a sideways topple onto the rug and a surprised face. **Call your pediatrician** after any head injury; a call is advised for every baby under 1, and **go to the ER now** if your baby vomits 2 or more times, cries and won't stop, or is awake but not alert afterward ([AAP](https://www.healthychildren.org/English/tips-tools/symptom-checker/Pages/symptomviewer.aspx?symptom=Head+Injury)).
- **Normal:** sitting with hands down at 7 months, or only when you place them ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-4-to-7-Months.aspx)). **Talk with your pediatrician** if your baby can't sit with help, or seems very stiff or very floppy ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Developmental-Milestones-7-Months.aspx)).
- **Normal:** a sit that holds for a minute and then folds. **Bring it up** if your baby uses one arm or leg much more than the other ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-8-to-12-Months.aspx)).

## For you

Your back is on the floor now too. The WHO's floor-based play several times a day is a recommendation for the baby ([WHO](https://www.who.int/news/item/24-04-2019-to-grow-up-healthy-children-need-to-sit-less-and-play-more)); it says nothing about the adult who gets down and up with them twenty times a day. Sit on a cushion with your back against the sofa, legs out, baby between them. Kneel behind rather than hunching over. When you stand up with the baby, bring them in close first, then use your legs. If you had a C-section, the lifting limit was the first 6 to 8 weeks ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000624.htm)), long past, but the floor lift is the deepest lift of the day and it's worth doing well.

If you're the partner: the mattress is yours tonight. Then take the next floor shift so she can sit on the sofa instead of against it.
