Baby demonstrating "W Sitting"

Have you noticed your child “W sitting”? W sitting is when a child sits on their bottom with both knees bent and their legs turned out away from the body. If you look down at the child’s legs from above, they form a “W” shape. This post explains what W sitting is, why it is a concern, and how to help your child sit in better positions.

What Is W Sitting?

In W sitting, the child’s hips are in extreme internal rotation. This position tightens the inner muscles of the hips and stretches the outer muscles. It can also put stress on the knees and ankles. For this reason, long-term W sitting may affect the position and quality of a child’s joints.

In addition, children who W sit may have weaker core muscles. Because the position is so stable, the child leans on their hip ligaments instead of using their core muscles to hold themselves up.

How to Break the Habit of W Sitting

So, how does a child break the habit? Anytime you see your child W sitting, give them verbal and physical cues that show how to sit another way. Here are some better leg positions.

  • Cross sitting: often called “criss-cross applesauce”
  • Side sitting: both legs bent to one side
  • Long sitting: legs straight out in front

Breaking the habit will likely take a while and a lot of patience. Always remember to praise your child for a correct sitting position. When your child chooses a better position on their own, a quick “I love how you are sitting” goes a long way.

When to Talk to a Professional

If your child W sits most of the time, or if sitting in other positions seems hard or uncomfortable, talk with your pediatrician. A physical therapist or occupational therapist can also check your child’s strength and motor skills and suggest activities to build core strength.

Frequently Asked Questions

Why is W sitting a problem?

The position puts the hips in extreme internal rotation and may stress the knees and ankles. It can also keep core muscles from getting stronger.

How do I stop my child from W sitting?

Offer a cue each time you notice it, show a better position such as criss-cross applesauce, and praise your child for sitting well. Because habits take time, be patient and consistent.

When should I see a professional about W sitting?

If W sitting is your child’s main sitting position, or if other positions are hard for them, ask your pediatrician. Therapists can help with strength and posture.
