S.C.
I had a very similar problem with my daughter when she turned 2. I made it about 2 months of that and was desperate for help and I called the pediatrician and she told me to give her 1 mg of melatonin at night. I was leery at first cause I am not a fan of just giving my children anything but the Dr. said that Melatonin is naturally produced by the brain but alot of times children's brains do not produce enough of it yet, it's what helps regulate their "clocks". So we tried it and it worked amazingly. In fact she is 3 now and still takes it before bed, We have tried to quit giving it to her and the night issues come right back! You can get Melatonin at any health food store. They are cherry flavored and she just chews them up. Goodluck! I know how stressful it is!!
