thanks for your replies....
I'm crazy for sure, but I'm thinking its got to do with his day time. I'm trying to stay consistent, though the last few days I've gotten EW's as well, which leads me to think he's OT/UT loop. he managed to make it to bt with a normal-ish a time (3h30) after a real good nap, so I'm fxing that i'll get a decent wakeup tomorrow morning to work with.
It could be temp, in that he's cold - but he's in winter onesie + sleep bag, and at that point he would be just right, neither too hot or too cold. he's managing to crunch four top teeth (the first ones) through at once.
I'm struggling with his first a time though, regardless of naps (the last few days the first am nap has been 20m,25m,35m today) the second nap has been great (2h). He has had middle a times of 3h,3h15,3h30 respectively. So fx tomorrow he'll wu after 5am and i'll be able to try some set nap times of sorts. I've been medicating before all naps and bt, but hasn't made any noticeable difference.
