My baby girl has completed 5 months yesterday. She doesn't have good head control. And I am worried. When I lift her in my arms, she does not control her head and leans backward from waist. Plz to reply for this:-)
There are no rules concerning babies. Each individual is special and has his own rules.
My twins wouldn't sit unsupported until they were 9 mo, after that they crawled and walked fast.
You can give her additional time and it is not a bad idea to consult your pediatrician.
