My baby is 1 year old he is not walking and not standing on his own but he is not crawling but moving in a sitting position. Should i be worried.

A. Yes you should be concerned about it because usually 9 to 11 months of age kids crawl between the age of 9 to 12 months kids can stand and walk with support and between the age of 12 to 17 months they walk independently right now your child is unable to walk with support also so I feel it’s a little delay in the growth
