Each morning after Adam's 4am feed, we find it difficlut to get back to sleep as he seems to have a different breathing pattern that is really noisey. Adam finds it difficlut to settle and makes grunting noises until his next feed at 8am and I'm not sure what is causing it. My Hubby had astma as a child and I can't help worry that it's maybe a start of that. I also think it could be the rapid eye movement type of sleep that I have read about as he is constantly moving his arms and legs at the same time. What do you think?
