We sleep trained our daughter at five months and it worked out great. She sleeps from 7pm-7am and takes 2/3 naps per day. Luckily her infant class at daycare has been very accommodating of our schedule, trying to get her to take as many naps as she will take. In the past couple months she has dropped to two naps a day, but once she turned 11 months, she moved to a new class at daycare. In this class, they have decided to switch to one nap a day. She is currently 11 1/2 months old and we are worried that this is not a good idea for the sleep training progress she has made. I've read that infants shouldn't switch to one nap until at least 18 months.

​

So far she still sleeps 7-7 (although most of the time she wakes around 6:30, but stays pretty quiet in her crib), but she is always very tired when she gets home from daycare and gets super fussy right before bed. Sometimes this affects our ability to feed her dinner because she's so fussy. What should we do about this? Will it be ok to go to one nap?
