My 2.5 yr old daughter has always slept well. Straight through. The last few days she has started sleep talking which leads to her crying and screaming at various times of the night. Nothing will console her. And during the day she has become real sensitive. Everything upsets her when she used to be hard as nails. I don't understand what's wrong. And I don't know how to help her! The only recent change is that I have started working full time from part time but that just means for her that she goes to childminder/nursery an hour earlier everyday. Any ideas?!
