Hi! I have spend HOURS reading other post about MANY topics, and LOVE this board. this is my first post, and first major issue with my little boy.'
He is now 3 months, 2 weeks old -- he has been sleeping through the night from 7-7 for well over a month. he was a terrible short napper, but I stuck it out every day and was able to lengthen his naps, and he now sleeps through them (he was very jerky, and would wake himself up, and couldn't fall back asleep)
We have been doing a 3 hours routine..and recently changed to a 3 and 1/2 hour routine -- he can stay up for about 1 1/2 at a time before crashing. he is very easy to put down to sleep -- and I usually still have to wake him to eat.
this is our routine:
7 am wake/eat/play
8-8:30 sleep -- I am trying to lengthen this awake time....he just can't stay awake for longer
10:30 eat/play
12 nap (again, he can't stay awake more than 1 1/2 at a time)
2 eat/play
3:30 nap
5:30 eat/play
7-7:30 bed
then a dream feed
the past week and a half he is waking around 11 and is wide awake and SCREAMING until 1 or 2. At first I thought something was wrong with him -- we turned on the light, and he was cooing and wanted to play. so, no, he was fine.
we have been doing PU/PD and it infuriates him and me, and my husband. we have done it for a full 3 hours all these times. I don't feel like he is hungry -- he will of course suck because he is so upset, but isn't taking a meal.
We have tried some accidental parenting and just holding him to sleep...but even then, he is very fitful.
This is a challenge because he can fall asleep on his own. to put him down for bed at night and for naps, we do the wind down routine, and drop him in his crib awake, but sleeping, and after 5-10 minutes he's out. no crying.
he has always nursed well, and I have plenty of milk.
any ideas on why this is happening?

and how to stop it???
no major milestones, illnesses, teething etc.
I don't want this to become a terrible habit.
THANKS!
