My 5 month old used to sleep great at night. He was going to sleep around 8, getting his dream feed at 11, and then sleeping through most nights until 5 or 6. Once he even slept until 6:30! I was so happy.
Now, he wakes up for his DF if we're not there right on time. And he wakes up angry! Then he will wake up at least twice more during the night, sometimes way more often. Last night's torture:
7:30 PM: nursed him
8 PM: sleep
10:30 PM: woke for not-so-DF
12:30 AM: woke, I ignored him and he went back to sleep.
2:30 AM: woke, I gave him a paci and he went back to sleep eventually (he does not take the paci anymore generally)
3:30 AM: woke, I nursed him
6:00 AM: woke, I brought him in bed and nursed him, put him back in crib, he fussed, I brought him back in bed, nursed him more, realized his overnight diaper had leaked, changed him, realized he was not going back to sleep for any reason - up, giggling, cooing, playing. Ugh.
We are, I think, off props. I do not nurse him to sleep, he is awake when he goes down. The paci is pretty much out of play (his doing, not mine!). He is still swaddled because the last attempt to take him out was disastrous. He has taken to banging his legs in his crib at night, sometimes while awake, sometimes while seemingly asleep. He does this with such force that we are afraid he is going to break his crib!
In terms of his days, he's not really on a 4 hour EASY yet. I know this is bad but I don't know how to fix it. The main problem seems to be that he is barely able to stay up for 2 hours. If we keep busy he can but otherwise it's hard for him. Then when I put him down, he will only very rarely sleep for 2 hours. So then he's woken up, it's only been 3 or 3 and a half hours, and I don't know what to do with him at that point. If I don't feed him and wait until it's been 4 hours, then once an hour after that has passed he's ready for bed again, and then up in an hour, and then the whole schedule is off. I don't know if it would make a difference in terms of his night wakings.
I should mention that I nurse him during the days Fridays-Mondays and he gets 2 7-oz bottles of EBM at play group Tues-Thurs and one bottle of formula. His DF has always been formula. We are waiting until 6 months to start solids. He's a big boy - above 97%ile in height and almost 18 lbs!
This is a big mess and I desperately need some help! Please

I am so tired. DH is threatening to make me do CIO with him because 3+ NWs is killing both of us!
