My son is 7 months but he didn't sleep properly n his body is not tight yet neither he is able to hold anything in his hands, not sit properly? Why this is happening n any about to worry it?

A. hi your baby is 7 months old now I hope he had no issues at birth or required nicu stay or is born prematurely.sometimes due to these reasons baby might require some more time but it's advisable to get your baby assessed by your pediatrician
