I might join in too. DS is 11.5 months and has always fought sleep, so judging whether to transition him has been very difficult.
Over the past 2 weeks, we have been doing one nap on many days. He STTN a few times early on, and now is waking 1-2 times per night.
About 2 weeks ago, he had a 3.5 A time first, then a 2.5-3hr nap, then a 20min catnap (which i woke him from), but BT was getting later and later, and he fought it. He also fought the 2nd nap. I tried to cut back the first nap, but it seems he has done this himself.
His current EASY is:
6.45 wake up, BF
8am breakfast
10.45/11am - BF and nap (usually 1.5 hrs, today 2hrs)
1pm - lunch
5pm - dinner, bath
6.30/6.45pm - BT
He has suddenly gone from 3.5-4 A time, to 4-6hr A time. He doesn't seem overly grumpy either (and he is a touchy/spirited baby).
I dont know whether the NW are him being OT. He doesn't stay awake long, but only last week he was having none to one wakeup per night. Could be teething, although the BT meds have not helped much.
