Step-by-Step Guide
Encourage Tummy Time
Start by giving your baby supervised tummy time from the first few weeks, gradually increasing the duration as they grow stronger.
Use Supportive Props
Once your baby is ready, use cushions or your legs to provide support as they practice sitting up. This helps them learn balance.
Practice Sitting Together
Sit on the floor with your baby and encourage them to sit between your legs for added security while they practice.
Monitor Progress
Observe your baby's ability to sit up over the weeks. They should steadily improve in strength and balance.
