Crayola, funny thing is he doesn't stand up he mostly lays down and looks like he's sleeping but screams. (I have monitor) I do have a fan in the room "and" the next room the other child is sleeping in. He was keeping her awake. I don't go back in until it's time to get him up. Mom says if I find something that will help him learn to sleep better she will "implement" it at home as well. She really is trying. She uses white noise at home as well. She lets him CIO and she says he does fall asleep, but once he wakes after about 20-25 min. he doesn't go back to sleep or stop screaming. I didn't mention he is part time 3-4 full days a week. He's been here for 6 days altogether. Next week is 4 days. I told Mom at pick up that I'd like him transitioned by Oct. 6 because I have another little full timer starting and want to have to transition him when he starts. I've also skipped his morning nap (partly cause he cries and only naps 20 min.). We walk and he can nap in the stroller in he's that tired, but he doesn't. He's fine waiting till 12:30 to go nap. I'm beginning to think it's just a wait and see type of thing. If he doesn't settle he'll be gone by end of October. Still open to any suggestions though.
