My ds went down tonight at 6.20 then woke up crying at 7.20. He had already had Calpol. I went up after 5 mins to put his mobile on and to make sure he wasnt too hot then i left the room and left him to cry. I usually leave him to cry himself back to sleep as its usually only for about 20 mins at most. But tonight he cried non-stop until just after 8 (40 mins). I went up every 10 mins to make sure he wasn't too hot and to put his mobile on but i didn't get him out as he got used to me doing that a few months ago and took a while to get him out of it. He wore himself out and fell to sleep on his own but this is the longest time i have ever done this. Do you think it is ok?
