My ds 8 has developed a going to sleep problem. He's always been good at going to bed and usually reads himself to sleep. But just recently he's been crying and saying he can't sleep because he's crying. I've gone through all the usual questions checking he's ok at school/friends/home etc he says he really doesn't know why he's crying. I think he's getting himself in a twist about going to sleep. I have used myself rescue remedy night spray and found it helped me and wondered whether to try it for him. Am I mad to even consider this??? Feel like he needs something to break the habit.
