my baby is 8month old she is not seating more than 1 minute so I want to know about that what's the age of seating without support?

A. If your baby isn't sitting on their own by age nine months, contact your pediatrician. It may be good to act sooner, especially if your baby is close to 9 months and is unable to sit with support. Development varies from baby to baby, but this may be a sign of a gross motor skill delay.
