Babies typically begin to sit up with some help around 6 months of age. By about 9 months, most babies can sit well without support and can get in and out of a sitting position, sometimes still needing a bit of help. By 12 months, babies usually can sit up independently without assistance

. Here is a general timeline for sitting up:

• Around 4 months: Babies can hold their heads steady without support and may begin sitting with help.
• Around 6 months: Babies start sitting with a little help or support, often in a tripod position.
• Around 7 to 9 months: Most babies sit up well without support and can move in and out of sitting positions.
• By 12 months: Babies typically sit up on their own without any help.

It's important to note that every baby develops at their own pace, so some may sit up a little earlier or later than this range

. Tummy time and encouraging sitting with support help strengthen the muscles needed for sitting independently
