Do I need to be concerned? My baby has not once made any effort to bat toys or grab or play with them. He will hold onto things you put into his hands but that’s about it. He was born 6 weeks premature so I’m not sure if that could be the reason. However all his other milestones were quite ahead. He’s started to try sit up by himself. Was tracking with his eyes at only a few weeks old and I have been told by family and numerous medical professionals he is very physically strong but I don’t understand why this kid has no interest in grabbing things!
