Please help anyone - I am at my wits end. DS who is now 13+1/2 weeks is now waking up frequently at night. He was going for 7-8 hours from about 7pm, having a feed between 3-4am and then going back to sleep till 6.30. We gave him formula for the night time feed at 10 (dream feed) in the hope that he would go longer at night. Boy did that backfire on us!He became really constipated and still woke up at the same times. We came off the formula to resolve his constipation which has now cleared,and he was OK for a bit though waking up every hour after his 3am feed with wind. The wind has been a constant battle for us and nothing seems to work - gripe water, infacol, changing my diet, fennel tea etc! But now the last 3 nights he seems to wake after only 3 hours asleep and then is up every 45 mins -1.5 hours. Sometimes he wants food, sometimes its wind and other times I can't tell what it is. He is also putting his fingers in his mouth and dribbling a lot, though there is no temp or redness or any sign of teeth.
We moved him from his moses basket into his cot before all this happened but we also stopped swaddling him with his hands in and waking him up for his 10 o'clock feed (as he wasn't really taking anything anyway), so its difficult to know what the trigger for all this was and it only seems to have got worse recently when we haven't really changed anything. He did have his injections 2 days ago though.
Is he going through a growth spurt maybe? He is on 3-3.5 hourly feeds and only sleeps for 45mins-1hr during day. Is my milk perhaps not enough for him anymore and perhaps we should try formula again? In-laws keep trying to tell me milk not enough and to try solids but particularly with his windy bowels I don't think that's suitable yet.
Anyone any similar experiences or advice. Please help - I am knackered and can't catch up in day as he only does short sleeps.
