DS is 8 weeks old and formula fed (anti reflux formula). He has never been a great feeder and generally speaking I wake him every 3 hours in the day a) to try and 'tank him up' so he'll sleep longer at night and b) because the formula takes time to prepare so it's easier if I know when to prepare it.
During the day he will take 3 or 4oz per feed and until recently this was the same at night (he wakes 3-3.5 hourly). Over the last few nights however he will only take an oz or so before falling asleep and then wakes 2 hours later wanting more food only to fall asleep again an oz later. I try waking him so that he'll take more but it doesn't work.
Consequently, I feel like I'm up all night feeding him, using umpteen bottles and wasting lots of formula. I've tried settling him in other ways but he'll only go back to sleep for 10 mins or so before waking again. I wonder therefore whether he's really hungry and whether I should try just giving him a drink of water so that he builds up an appetite and is more likely to take a full feed next time he wakes - hopefully leading to longer periods between night feeds. Any advice or similar experiences would be much appreciated.
