how old should my baby be to sit up on his own
One of the first developmental milestones that new parents look forward to is the day their baby learns to sit up. Most babies will learn to sit by themselves somewhere between 6 and 8 months, however, it can happen as early as 4 months or as late as 10 months with no cause for alarm. As soon as your baby can support and control her head and has mastered rolling from back to belly, she can start learning to sit.
