By When Should Baby Sit up?

At 4 months, a baby typically can hold his/her head steady without support, and at 6 months, he/she begins to sit with a little help. At 9 months he/she sits well without support, and gets in and out of a sitting position but may require help.

How can I help my baby learn to sit up?

To help your baby sit up, try holding onto their arms when they're on their back and gently pulling them up to a sitting position. They'll enjoy the back-and-forth motion, so add some fun sound effects to make it even more exciting.

Is it OK to sit a 3 month old baby?

You may want to wait until your baby is closer to reaching the sitting milestone to use a baby seat. Instead of propping your baby at three months old, consider waiting until sometime between 6 and 8 months. And don't rely on this seat as baby's sole tool for practice.
