Does not track
My son is seven weeks old and he does not track an object with his eyes. In fact, he will hardly even look at an object held in front of him, even if the distance is only about six inches. He has a play mat and he will spend a lot of time banging the toys to make them swing around. He seems to enjoy the sensation of touching them and the noise that they make, but he almost never actually looks at the toys dangling over his head. He just keeps his head turned to side, staring into the middle distance. Also, it seems as if he whacks at the toys just by feeling for them.
He will make some eye contact with my husband and me during feedings when he is snuggled very close to us, but it's extremely difficult to catch his eye at other times. Should I be worried? What should I be doing to help?
