He used to be great at going to sleep - for some reason, for the past week, after his usual routine, he starts shouting and crying and throwing things around his bedroom - I am worried that he is going to hurt himself so it is difficult just to ignore it. Tonight he put his light on , pulled his socks etc out of the drawer, books on floor. I went up calmly and made him put them all back, but after another couple of times of screaming, I lost it and shouted at him to get to sleep etc! How can I stop myself losing it with him? He is not going to sleep until midnight now...
