Yes, he does have a night light. I know he should be discouraged from coming into Mum's bed, but life with an autistic child is hard enough , let alone trying to cope on little sleep, so I understand your daughter's solution Swanny, and a bit of me thinks they should go for "the easy life" ...that's a joke! He stayed overnight this weekend and slept in a double bed with his sister. No problems, yet I appreciate the relationship is different between Grandparents and DGS and Parents and DGS, and sleeping with his sister on a regular basis is definitely not an option! I did some research on the net last night, always a dangerous thing, and some parents have tried Melatonin with some success. Have any of you heard of this. I don't know if I dare mention it to my daughter! Thanks for your replies, I knew you had a GS on the spectrum Swanny, and judging by media reports in the last couple of years, there must be many of us around!
