Hi there, sorry it didn't go so great tonight.
Yes I agree, she is OT for sure. An OT baby will cry more and fight bedtime more than a well rested one. I wouldn't be surprised if it also amplfies the SA too.
You mentioned before that you woke her up from her nap-was there a reason for this? IIWM, I wouldn't be waking her up. I would let her sleep as long as she wants to sleep, especially on one nap.
You know she's tired from the past few days and we know that OT takes a while to get out of as it accumulates, so one good night or one good nap won't put her in clear after several days of OT.
You can try one of two things-
a) go back to 2 naps
b) try one nap again but keep bedtime much earlier. Like I mentioned before, when moving to one nap (especially this early, many babies don't fully transition until somewhere between 15-18 months) you really need to compensate for the lost sleep and longer A times. I know it sounds crazy, but aiming for her to be *asleep* by 5:30/6:oopm will help you out quite a bit right now. It's not forever, but it will be for a bit until her body adjusts. But keep in mind she might just not be ready for 1 nap yet.
Fingers crossed for a better day tomorrow!
