DD is nearly 6 weeks old and never looks at anyone in the face. When held close to my face (while I smile, talk and sing to her) she looks around the room and ignores me. Even if she looks in someone's general direction, it seems like she's looking "through" them and not really at them.

I can definitely see her getting interested in other things. She'll look at her mobile and herself in the mirror for 15 minutes or more, but faces do not seem to interest her at all.

Is this normal? I thought babies were supposed to like looking at faces?
