My 9 week old baby doesn't look at me?

All you should be worrying about is if your baby is healthy. She will smile and coo when she is ready. Every child develops differently. My daughter said her 1st word at 3 months but didnt walk till 13 months. My friends child didnt say his 1st word till he was 12 months but was walking at 10 months. Just enjoy your baby, they grow too fast!
