I had my baby early at 28 weeks , he’s now 31 weeks . My concern is when I put my finger on his hand he doesn’t really want to grip on it and always moves his hand away and usually his hands are open never really in a fist. Is this all normal ? This is my first experience with a preemie, maybe I’m just over thinking . He is doing physical therapy and they say he’s doing great. I guess I’m just comparing to my other son who was full term.
