We have tried to move it up do many times and nothing has worked. We had been turning lights out at 8 but he wouldn't fall asleep until close to 9. We are sitting in his room in the dark with him because he's been having horrible separation anxiety. We tried to put him to bed at 745, then 730 tonight. He just plays in there (and occasionally fusses) and freaks out if we leave until 9. He isn't napping well at school either and I'm sure he needs more sleep but I don't know what to do! He's 18 months old.
