My ds2 Isaac started using this cot comforter with mickey mouse on it that I bought off ebay when he was under 6 months. He just turned 6 in sept and he still takes it to bed with him every night and has it over him when watching tv. He is very attached to it. We have restrictions on it though. We don't allow it to leave the house unless we are staying somewhere overnight or if he is sick and going to the Drs..

Ds3 Jacob also has one which we think started because Isaac had one. his has teddy bears on it and he sleeps with it everynight. He is not as attached to his as Isaac is but still close enough
