Our DS has slept excellently for around a year (he is nearly 5 so an older reception kid). About 10 days into school he started getring out of bed 3-4 times a night and in desperation after nearly a week of both working on 4ish hours a night we've made him a "bed nest" on the floor which he transfers himself to around 3am.
If this happened to anyone else - I believe it's separation anxiety - how long did it last?
