Hello everyone. I am new to Mumsnet and this is my first message. Any advice would be appreciated. My ds is 5 weeks old tomorrow. He was a big boy at 9.2lb when born so he seems to be permanently hungry. He's just guzzled 7floz (the most in one sitting yet). I've been following the guidelines on the box (aptimil) but I upped it as he wasn't lasting long on 5floz. Anyway, at his 10.30 - 11.30 feed we can't get him to finish his bottle even though he should be hungry. We've tried waking him up (very hard), and we've tried leaving him to wake up by himself, to ensure he's fully hungry, which works better but tends to be nearer 11.30 (after a feed at 6.30ish). The later the feed, obviously the later he wakes in the night (usually around 2.30 - 3.30). If we could get him to finish his bottle I think we could be close to getting him to sleep through or am I wishful thinking at this age. Another thing, when I feed him in the night, he nods off, I put him down, he does a very good impression of being fast asleep then I bring him back into our room, which is very dark, at he starts making these grunting, pushing noises basically for the rest of the night. I've checked, and his eyes are closed but it can't be proper sleep, not with all that wriggling going on. Can it be the forumular - would chaning make a difference? I'm using Aptimil. Sorry to blather on. It's all guess work I guess, until you can ask them what's wrong!
