My 12 week son goes to bed at 19:30 he wakes at 12:30 and 3:30 the only way to settle him is a feed (6 oz formula) we have tried a dummy but spent putting it back in every 10 mins or sooner for over 2 hours, at least he goes back to sleep better after a feed although I am sure he doesn't need it as can go 4 to 5 hours at times in day. The worst part is he is wide awake at 5:30 and won't settle back to sleep, again tried dummy but he wakes every 5 to 10 mins when this falls out. Any advice would b very much appreciated. I also have a 4 yr old so am extremely exhausted.
