sorry to post on SN but things my ds was doing last night have got me really worried now. He's had a gut problem for a while now, he's nearly 8 months old, and he's never been able to support himself on his front, or roll. in every other way he's lovely, great eye contact, laughs, but he has started to thrash his head violently from side to side. He started doing it a bit when he was tired, but last night he did it for about two hours on and off, and he did it even in his baby bouncer. I don't know whats happening to him. I don't know if anyone else has seen this behaviour, but i feel like i'm losing his lovely personality. Its always been a big struggle to get him to drink enough, bfeeds for short times only and hates anything else, don't know if this has anything to do with it.
