when can babies sit up on their own

Babies can start sitting with support as early as 4 to 6 months old. Most babies begin to sit up independently, without support, between 7 to 9 months of age. By around 9 months, many babies can sit well without help, and by one year, they can generally get themselves into a sitting position on their own. The timeline varies as every baby develops at their own pace, but typically independent sitting occurs around 7 to 9 months.
