What age should a baby try to sit up on its own?

Varies: Most infants are beginning to sit up without support around 6 months of age. It may take until 9 months of age, though.

6 months: Most babies can sit up by 6 months, but there are a few signs that tell us that they're making progress: -tripodding: putting hands out in front to support themselves -propping: putting hands out to the sides to prevent falling over.
