My 4 month old son was doing so well with only waking once at night between 2-3am and then not again until he was up for the day between 6:30-7am. Since last Thursday night he has been waking around 1am and again at 5am. The one thing I have noticed is he is not finishing a full bottle at 5am waking. Also, he falls asleep in my arms taking his bottle, but when I lay him down he wakes up immediately and starts talking and playing. UGH! I walk away and just leave him be until he starts fussing then I go in and put the paci in and he usually goes to sleep. Therefore, not only is he waking up twice again, but also not wanting to go back to sleep. I will add that 2 weeks ago he was diagnosed with a MPI and his formula changed to a formula that is amino acid based and very easy to digest. This is in addition to already having reflux that he is being treated for. He is eating so much better and is so happy now so I hate to complain. I am wondering if this change in formula is what is causing the multiple night wakings because maybe he is not staying satisfied as long. I try and feed him as much as he wants, but he still only takes about 28oz a day. He is 15lbs 8oz. He doesn't want to eat when he gets up because of the 5am feed and therefore, he ends up taking a bottle and going down for a nap around 9 which then messes up out EASY routine. Any ideas as to what is going on and what I can do to fix it?
