When does a baby sit up? Is supporting them with pillows harmful?
⚡ Short answer: At 3 months, propping a baby up with pillows puts strain on their spine—instead, give plenty of tummy time. Babies typically sit independently between 4-7 months.

I prop my baby up with pillows to sit, but people say early sitting can cause harm. When will my baby sit on their own?

It's completely natural to worry about this. At 3 months old, your baby's back and neck muscles aren't strong enough yet, so propping them up with pillows adds extra strain to their spine and doesn't speed up development—it can actually make things harder.
Babies typically start sitting on their own between 4-7 months. First, they develop the foundation through rolling, crawling, and other movements that work the core muscles. Signs your baby is ready include lifting their head while on their back and leaning on their arms while on their stomach.
Right now, the best thing you can do is give plenty of tummy time. This is the foundation for all motor development, including sitting. If you want to sit your baby up, do it briefly in your lap or in a high chair with proper support—not with pillows.
If you don't see signs of independent sitting within 2-3 weeks, you can check with your pediatrician.
