If you've watched your child plop down with their legs splayed out in a “W” and then read online that it's terrible for them, take a breath. W-sitting is extremely common, and the truth is more nuanced than the scary headlines suggest. Here's how an occupational therapist actually thinks about it.
What is W-sitting?
W-sitting is when a child sits on their bottom with their knees bent and feet out to the sides, so their legs form a “W.” Lots of kids do it some of the time — it's a stable, easy position that takes little effort to hold.
Why do kids W-sit?
That stability is exactly the point. W-sitting gives a wide base of support, so children who have lower core or trunk strength often default to it because it lets them stay upright and free up their hands to play without working their middle. In other words, it's frequently a sign that sitting other ways is harder for them.
So is W-sitting actually bad?
Occasional W-sitting in a typically developing child usually isn't something to panic about. The concern is when it's a child's main or only way to sit, because it lets them avoid using the core and trunk-rotation skills that support balance, coordination, and later handwriting — and over time it can affect hips and posture. The position itself is less the issue than what relying on it may signal.
When to be concerned — or see an OT
- Your child almost always W-sits and resists other positions.
- You notice low muscle tone, frequent slouching, or fatigue with sitting.
- There's clumsiness, poor balance, or difficulty crossing the middle of the body.
- Handwriting, coordination, or core strength seem behind peers.
W-sitting on its own rarely “damages” a healthy child — the value of noticing it is what it can reveal about underlying strength. An OT evaluation sorts that out.
If W-sitting is your child's go-to, an OT can check the core strength behind it.
Better positions to encourage
- Criss-cross (“crisscross applesauce”).
- Side-sitting, with legs to one side (alternate sides).
- Long-sitting with legs straight out front.
- Sitting on a small stool or bench that engages the core.
How occupational therapy helps
If W-sitting points to weaker core strength or coordination, OT builds those foundations through play — and your child naturally stops relying on the W. An evaluation requires a referral from your child's primary care provider (faxed to 901-589-9001).
