I was working peds ICU 2 years out of nursing school
. One of our little patients had expired. We brought the family in to be with the little girl. Well, they were all crying, and one of them tore off a piece of the eggcrate mattress and said "and this would have been just like cake to her", and they all started wailing. We, the nurses, found out later the little girl had the pica thing going for foam rubber.
