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 she’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. These muscles develop gradually from birth. You’ll see your baby strengthening these muscles by lifting her head when she is lying on her tummy.
You can encourage your baby to develop these new skills by giving her as much time to play on her tummy as possible. Try giving your little one small amounts of tummy time soon after her birth.
During tummy time, try to get your baby to look up by using colourful and noisy toys, or by making funny faces or sounds. This will help her to develop strong neck, back and shoulder muscles which will help her to gain good head control.
Like any new skill, sitting takes practice. In the early days, your baby will need to lean forward onto her arms for balance. Make sure she has plenty of soft pillows or cushions around her in case she topples over. As her muscles get stronger she will be able sit up unsupported and enjoy a whole new outlook on the world.
Bear in mind that babies develop differently, some more quickly than others. If you’re concerned about your baby’s development, or if she isn’t sitting up independently by nine months, talk to your GP or health visitor.
