My DD hasn't been able to get to sleep on her own for the last few nights (and to make things worse she's just moved into her own bedroom) without crying for at least an hour.. I do go in to her every 10 mins or so but she just gets worse when I leave the room again. The other night I left her to cry for about 15 mins and when I went in she started to throw up everywhere...it was her tea from 4 hours later mixed with her recent bottle....could it be possible she got herself so worked up that she made herself sick?
