๐ŸŽพ Ways to Encourage Sitting Up Independently

Try these activities to support your baby's development:

Supported sitting practice

Use a Boppy pillow or your legs to provide support while baby practices balance

Tummy time progression

Strong tummy time skills build the core muscles essential for sitting

Sit and play

Place toys in front of seated baby to encourage reaching while maintaining balance

Tripod sitting

Let baby practice sitting with hands on the floor for support, gradually removing assistance

โ“ Frequently Asked Questions

When should I start using a high chair? +
Most babies are ready for a high chair once they can sit with minimal support, usually around 5-6 months. Look for a high chair with good back support and a footrest.
Is it okay to prop my baby up to sit? +
Brief propping with pillows is fine for supervised play, but don't use devices like Bumbo seats for extended periods โ€” they don't encourage natural core strengthening.
My baby can sit but keeps toppling over โ€” what should I do? +
This is completely normal! Place pillows around baby for safety. Balance takes time to develop. Practice sessions of a few minutes several times daily will help.
