Do you think the whole idea of comforting the child with your T is weird, or just that he wants to "come into your room"? My T and I do IFS--internal systems therapy and that deals with parts of the personality, often child parts. Many times she has had me close my eyes and visualize her and my adult Self holding the baby or child together. She's sometimes had me picture a few other nurturing people all in a circle "passing the baby" from one to another, holding and comforting it. The baby being me, of course.

At first I thought this was so silly and useless, but I tried it anyway, and it does help!! Sometimes we fight against tenchiques that seem ridiculous, but they end of helping. I would give it a try!
