My 17 week old LB still cannot stand tummy time. There are no signs of him lifting his head or a mini push up. He screams after only a minute and just squirms and kicks his legs. I'm trying not to get hung up on developmental milestones but it's getting a little worrying now as everything I've read has said by 4 months they should be able to lay in there tummy in a mini push up and look around. Other people's babys at baby group and massage are younger than my son and they can all do it, some are even rolling over but Reggie is just nowhere near.
Should I be worried?
