good morning sir/madam.my baby 10 m 10 days old. she sat when I was put sitting position with out support long time(20-30 mins) but not she turns lying position to sitting anything problem

A. I think there is some issue with the sitting of the child maybe it’s due to deficiency maybe it’s due to another issue so please check with your doctor because by this age kids can basically rather I should say by the age of 8-8.5 months kids can sit on their own only without any support so please check with your doctor
