I can't shake the feeling there is something going on with my 6 month old baby that isn't how it should be. He doesn't really babble at all, doesn't like tummy time, is sick loads, examines his hands a LOT and will just lie there staring into space. He also still clenches his thumb in his fist a lot which most babies grow out of by 2 months, and does the most awful poos and wind. He is a dreadful sleeper in the day and not much better at night. He seems like a newborn still in many ways (although he has learned to sit up and roll, just about). But sometimes he's almost too easy, if you know what I mean.
Back story is that I had a difficult pregnancy mental health wise, and was very stressed, and I worry that it's had an impact on him. I cannot tell if there is a genuine concern there or I'm projecting my guilt onto the situation and looking for problems. I'm struggling to trust my gut.
