What use to work for me is PLENTY of night lights, very special blankets and
stuffed animals. Also, every time it would happen I would make sure to do
the EXACT same thing I had done the last time, same words, same tone, same way of holding him. I would talk in a low, calm voice very slowly. All of his blankies and stuffed animals went to bed with him and I made sure that he understood they were HIS and that they would be there.
