when does a baby sit up
Most babies begin learning to sit up at some time between four months and seven months. Your little one could be sitting well without support by the time sheâs nine months old. Sitting takes your baby a step closer on the road to walking. Sitting usually comes after your baby gets the hang of rolling over and before she learns to crawl. Don't worry if your baby does things in a different order. All babies develop at their own rate and in different ways. To be able to sit by herself, your baby needs to develop strong head and neck muscles.
