After nearly 2 years of broken sleep my ds2 finally started sleeping through at 22mo. But after 3 months of this he has started night waking again - it started being just once but last night it was 4 times! He was given a teddy a few nights ago which he sleeps with but this seems to have started off the night waking for some reason e.g he loses it and wants me to help find it. I also think he lays on it so wakes up uncomfortable. I've tried not giving him it but he asks for it at bedtime and I can't refuse him a comfort toy. Any ideas?
