I have a 2 1/2 yr old daughter who was recently diagnosed with autism. At around 18 months old she all of a sudden stopped sleeping. We would maybe be able to get her to have a 45min nap in the morning, other than that she never slept. I have started giving her a small amount of melatonin before bed, which has helped to get her to sleep, but she wakes up all night long screaming. I am wondering if this is normal and if anyone else has gone through the same thing with their child on the spectrum? Thanks in advance.View Thread
