Why does my child W-Sit?
Children may sit in the W position because it provides them with a wide base of support during play and other activities. In this position, they require less effort to keep their posture upright.
The W-sit position is quite common in children. According to the International Hip Dysplasia Institution, this position is often observed around 3 years of age, and then naturally fades out of routine as the child grows.
Is W-sitting normal?
W-sitting is normal when children are moving and changing positions frequently.
When is W-sitting a problem?
W-sitting is a problem when this position becomes one of the only ways your child is sitting.
Prolonged W-sitting can lead to:
- Issues with balance and coordination
- Hip dysplasia
- Changes in bone structures during development
- Knock knees
- Pidgeon Toeing
- Abnormal walking patterns
- Muscle tightness
- Limited range of motion
- Poor posture

- Criss Cross Sitting
- Side-sitting
