Unable to sit unsupported at 7 months.

Hi mommies. Turning 8 months napo si lo ko this coming july 20, 2021 and he still cannot sit on his own. Okay lang po ba yon? He can sit po pero with hand support. Kapag walang support po natutumba siya. Hindi pa siya maka upo mag isa. #pleasehelp #1stimemom #firstbaby #advicepls
