My boy is 22 months and has not napped for the past 2 weeks. Schedule is exactly the same as he wakes at 7 and put him down at 12 for his nap. Room is dark with white noise. We read a book before bed in low lighting which usually worked. He sits and screams now until I go get him no matter how long I wait. Tried putting q book and Teddy in his crib but still won't nap. Any suggestions and how do you deal with an extremely tired, crying child all pm. He goes to bed at 7 and sleeps through perfectly.
