some of you might know my ds has had a gut problem for a few months now and i've been a bit hawkish about looking at his development. He is still hopeless at rolling, cries when i put him on his tummy, altho he will roll from front to back, never the other way round. One thing i've read from other threads is that a baby should mimic things you do by now. I've tried sticking out my tongue, he just smiles, i've tried making noises, actions, he doesn't copy any of them. He isn't a great babbler, tho he can if he wants. Should he copy me more? Anyone else's baby like this? Starting to really worry.
