Since December my 3 year old has been fighting bed times, when she eventually goes to sleep she wakes between 10 and 12 every night without fail.we have tried adding a night light, white noise, transisitioning to a big bed which all hasn't worked. Now when she goes into her bed we have to lay with her till she falls asleep, then sneak out without waking her, which doesn't always work. I am so exhausted by it all and just don't know what to do next to try help her sleep. She used to sleep so well from 6 months all night no problem, don't know what's happened am I missing something is there something more I can do ?
