My 2 almost 3 year old I think has autism and I can't get her to sleep. Dr prescribed 1 mg of melatonin but that doesn't help ( she stays up until 4 am most of the time and no naps during the day with lots of walks to try to ware her out also give her the melatonin at 8pm ) She gets up and turns the light on and thinks it's a game. So right now we have tape over the light switch. Any help for advice ? Also how does everyone cope with destructive behaviors? She also hits her sister and tries to grab her toys and hit her. I know she's probably jealous but we do 1:1 with her so she knows we love her and she gets that time but it's hard to know what else to try? I'm one exhausted mama.
