Sleep's been good for ages, usual wobbles with snot and teething, but very good at going straight to sleep at bedtime. Except for the last two weeks. I put her down awake as usual, and instead of lying there and going to sleep, she's playing with toys, looking out the window, singing. After an hour and a half she'll start crying, probably because her comforter, dummy, and everything else has been thrown on the floor and she won't sleep without them. It's taking two hours to get her to sleep!
Usual day is up around 7.30, nap at 11.30, I'll wake her at 2 if she hasn't already woken. Fifteen months old. No idea what to try. Any suggestions?
