Dd is 3 months old.. She is 15 weeks but was 6 weeks early..
She won't lift her head. Ever.
When I put her on her belly I try an make her lift her head by talking to her but all she does is suck her hands and goes to sleep.
I have put a rolled up blanket under her chest and still she won't lift it she just goes to sleep..
Any tips I don't want her falling behind.
