Communication skills are extremely limited. A significant problem for the family is his irregular sleep habits. Two-three times a week he will wake between 1 and 2 am and go to his brother's room, climb in his bed and fall asleep. The brother then usually wakes, calls his parents. Other nights he will sleep to 4 or 5 am and then is up for the day.
Any thoughts are much appreciated.
Bonnie, You might give a try to having the child sleep in a sleeping bag for the might. Less tactile distraction than the loose blankets for one thing. I have seen it work well in the past. He sounds like a perfect candidate. Communication skills are extremely limited.
