DS is 17 weeks and was sleeping from 7pm through to at least 5am without waking ~(very lucky I know!) but the past couple of weeks he's been waking up religiously between 2and 3am, wide awake, talking and singing to himself and then gradually getting more and more agitated until we give him his dummy again. He'll then wake up evey half hour or so when his dummy falls out. It then gets to 5/ 5.30am and we have to bring him into our bed just so that we all can get some sleep. He's quite a big baby for his age, must be around 18lbs now. He takes 8oz bottles at 7-7.30am, 11am, 2pm and 6pm wih perhaps around 3oz at 4pm if he's fretful. When he wakes during the night he's not crying for food. A friend has suggested we go back to giving him another feed at 11pm (which we'd stopped when he started to sleep through from 7pm). I'm not sure whether we should or not. Others have suggested we start to wean him, but I think I should wait unitl he's 6 monhts. Sorry to babble on, but this is driving us mad. What do others think? Should we go back to giving him a bottle at 11pm in the hope that he'll go back to sleeping through?
