As parents, we often notice our little ones adopting various sitting positions as they play and explore. One position that frequently raises concerns is “W sitting,” where a child sits on their bottom with their knees bent and legs splayed out to the sides, forming a “W” shape. While this position is common among young children, it’s important to understand its implications for development and when you might need to be concerned.

What Is W Sitting?
W sitting is a posture where a child sits on their bottom with their legs bent and positioned outward. This position can be comfortable for children because it provides a wide base of support, making it easy for them to transition into other movements like crawling or standing.
Is W Sitting Normal?
For many children, W sitting is a natural and temporary phase of development. It’s especially common in toddlers who are still developing their motor skills. Most children will naturally outgrow this sitting position as they gain strength and coordination. However, prolonged or habitual W sitting may warrant closer attention.
Potential Concerns with W Sitting
While W sitting is not inherently harmful, there are several reasons why it may be concerning:
- Muscle Imbalance: W sitting can promote tightness in the hips and knees and may lead to muscle imbalances. This position can inhibit the development of core strength and stability, which are crucial for other motor skills.
- Limited Hip Mobility: Regularly sitting in this position may restrict hip movement and affect a child’s ability to sit cross-legged (or in other positions) as they grow.
- Impact on Posture: Prolonged W sitting may lead to poor posture, which can impact a child’s overall physical development and alignment.
- Delayed Motor Skills: If a child favours W sitting over other positions, it may delay the development of important skills like crawling, walking, and running.
When to Be Concerned
While occasional W sitting is generally not a cause for alarm, there are specific signs to watch for:
- Consistency: If your child consistently prefers W sitting over other positions, it may be worth discussing with a healthcare professional.
- Developmental Delays: If you notice delays in gross motor skills, such as crawling, walking, or climbing, it is advisable to seek guidance.
- Discomfort or Pain: If your child complains of discomfort or pain when sitting in various positions, consult a healthcare provider for an assessment.

Encouraging Healthier Sitting Positions
If you are concerned about W sitting, there are several strategies you can implement to encourage healthier sitting habits:
- Model Other Positions: Encourage your child to sit cross-legged, in a “crisscross applesauce” position, or on their knees. You can model these positions during playtime to make them more appealing.
- Provide Supportive Seating: Use cushions or benches to create a comfortable environment for sitting in healthier positions.
- Incorporate Movement: Engage your child in activities that promote core strength and mobility, such as climbing, crawling, and playing on the floor.
- Limit W Sitting: Gently remind your child to change positions if you notice them W sitting for extended periods.
- Consult Professionals: If you have ongoing concerns, reach out to your paediatrician or a physiotherapist for personalised guidance.
Conclusion
W sitting is common among young children and, in many cases, is not a cause for concern. However, it is important to monitor your child’s habits and development. If W sitting becomes a persistent preference, or if you notice developmental delays or discomfort, consulting with a healthcare professional is advisable.
By fostering a variety of sitting positions and encouraging movement, you can help support your child’s physical development and promote healthy habits that will benefit them as they grow. Remember, every child develops at their own pace, and being attentive to their needs is key to their well-being.
