My 11 week old baby doesn’t play with rattles. He doesn’t track rattles while I make sound of it. Is it normal?

A. Kids actually gain their precise vision after completing the time of three months I would suggest you to wait till then let the child have a very clear vision with which you will actually see how things are going to change the child is going to follow the objects that you were expecting and other things into the growth of the child would be more evident
