Becky.,
It worked out! Thank you so very much. He's settled into the new routine, school and all. We've had a few rocky naps or nights (knock wood, not many), mostly seem to be due to the colds that have caught him... although really, he powers right through most of them during the day, the coughs have woken him early some days or naps. He's doing well in the BBB for naps (although he does get up and come out when he wakes, instead of calling for Daddy, DH hears the bedroom door close and finds DS standing outside his room waiting to be picked up. Still in crib at night.
Day now looks like this, most days (posting in case it helps others).
6:45 wake him up if not already up
7:00 breakfast
7:30 off to preschool
9:00 snack at school
11:15 lunch/snacks on way home
11:45-1:00 or on a good day, later than that, nap (sometimes as long as 2 hrs, though that's maybe one or two times/week)
after nap, some snacks if hungry, if not, those are mid-afternoon
5:30 - dinner
6:15 - bath, bottle/stories, bed start
7:00 - normally asleep
I think the early naps and early bedtime have been key to helping him get over the OTs and get the sleep he needs. We wouldn't have seen that combo without your help, Becky!
It would be lovely to shift bedtime later but not going to risk it now! lol
