# Day 308: Cruising to standing alone

> Standing alone starts anywhere from 6.9 to 16.9 months and walking alone from 8.2 to 17.6. The moment between cruising and standing is letting go of the sofa for a second. Count it, no goal.

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.

The hands are on the sofa all day now. Sometime soon one of them lifts, and then both, and for a second there's a baby standing in the middle of the room with nothing holding on. Today is that second: how wide its window is, and how to help without holding.

## Heart

In the WHO's study of 816 healthy children in Ghana, India, Norway, Oman, and the US, standing alone started anywhere from 6.9 to 16.9 months, and walking alone from 8.2 to 17.6 months, 1st to 99th percentiles ([WHO Multicentre Growth Reference Study Group, 2006](https://pubmed.ncbi.nlm.nih.gov/16817682/)). Your baby is 10 months old, which is inside the standing window and nowhere near the end of it. What most babies do by 12 months is pull up to stand and walk while holding on to furniture ([CDC](https://www.cdc.gov/act-early/milestones/1-year.html)); standing with no hands isn't on that list. If it happens this month, it's early-ish. If it doesn't happen for months, it's on time.

## Head

The sequence, from the AAP: pulling up to stand, often before they know how to get back down, then cruising sideways along furniture, then wobbly first steps, which many babies take around their first birthday ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-8-to-12-Months.aspx)). Between cruising and steps is the unlisted move: a hand comes off to reach for a toy, the body balances for a beat, the hand goes back. The AAP's one coaching tip for this stage is about the other direction, showing a stuck baby how to bend their knees to sit down ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-8-to-12-Months.aspx)). Getting down safely is what makes letting go safe to try. Walking itself is learned by volume: filmed during free play, 12- to 19-month-olds averaged 2,368 steps and 17 falls per hour ([Adolph et al., 2012](https://pubmed.ncbi.nlm.nih.gov/23085640/)).

## Body

The setting does the coaching. CDC suggests placing your baby near furniture they can safely pull up on ([CDC](https://www.cdc.gov/act-early/milestones/9-months.html)), and safely means anchored: bookcases, dressers, and TV stands fixed to the wall ([AAP](https://www.healthychildren.org/English/safety-prevention/at-home/Pages/Home-Safety-Heres-How.aspx)), and the crib mattress at its lowest position before your baby learns to stand ([AAP](https://www.healthychildren.org/English/safety-prevention/at-home/Pages/Make-Babys-Room-Safe.aspx)). The guide's activity is [Cruise to the toy](https://chorevia.com/learn/7-12-months#cruise-to-the-toy); today adds a count.

## Try today

### The let-go second

- **Time:** 2 minutes, once today
- **From the guide:** [Cruise to the toy](https://chorevia.com/learn/7-12-months#cruise-to-the-toy)

1. Stand your baby at the sofa on a rug, both hands on the cushion, and kneel behind them with your hands hovering at their ribs, not touching.
2. Hold a toy a little in front of them, at chest height, so reaching for it means a hand has to leave the sofa.
3. The moment the second hand lifts, count out loud, slowly. Stop counting when a hand goes back or they sit. Write the number, even if it's zero.
4. Once, show the sit-down: a hand on each hip, bend the knees, bottom to the rug, "Down!" ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-8-to-12-Months.aspx)).
5. Do it again next week, not tomorrow. Standing alone runs from 6.9 to 16.9 months ([WHO Multicentre Growth Reference Study Group, 2006](https://pubmed.ncbi.nlm.nih.gov/16817682/)); there's no goal and no pass mark.

**Make it work:** Hovering, not holding. A baby held up by the armpits isn't balancing, and the balancing is the lesson.

## Watch for

- **Normal:** both hands glued to the sofa all month; standing alone has until 16.9 months in the WHO's range ([WHO Multicentre Growth Reference Study Group, 2006](https://pubmed.ncbi.nlm.nih.gov/16817682/)). **Ask about a developmental screening** if your baby isn't pulling to stand by 12 months ([CDC](https://www.cdc.gov/act-early/milestones/1-year.html)).
- **Normal:** a let-go that ends on a diapered bottom with a thump and a surprised face; the study's walkers fell 17 times an hour ([Adolph et al., 2012](https://pubmed.ncbi.nlm.nih.gov/23085640/)). **Call your pediatrician now** for any head injury in a baby under 1 year, even if your baby seems fine ([AAP](https://www.healthychildren.org/English/tips-tools/symptom-checker/Pages/symptomviewer.aspx?symptom=Head+Injury)).
- **Normal:** cruising left along the sofa and not right, for a day. **Talk with your pediatrician** 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

The range, not the calendar. The birthday is circled on the wall and it has started to look like a deadline, because the word "first" is attached to "steps" in every song and card. The WHO's window for walking alone is 8.2 to 17.6 months ([WHO Multicentre Growth Reference Study Group, 2006](https://pubmed.ncbi.nlm.nih.gov/16817682/)), which is to say the birthday sits in the middle of it, not at the end. The only line that has a job is the 12-month one about pulling up ([CDC](https://www.cdc.gov/act-early/milestones/1-year.html)), and your baby is at the sofa all day. The calendar is for cake.

If you're the partner: if the let-go second happens while she's at work, film it, send it, and then don't say "you missed it." Say "it'll happen again tonight," because it will.
