I am going to attempt to transition my 2 year old into a bed in the next month. In his crib he has a small blanket and a couple of stuffed animans but I am not sure what to do in his new bed? Do I introduce a pillow and sheets and a comforter? Is that too much? He sleeps fine without any of those things right now and still rolls all over the place so I don't even know how effective bedding would be.
