My 2 yo hates sleeping in his bed. we try to let him cry but he gets so upset times he vomits. tonight there were pink pieces in vomit. blood or food?

Cry it out: Probably food. Try to start putting him down for naps by himself. Day time is often easier for parents. Nighttime institute a routine: bath, bedclothes, brush, books, bed. Sit with him while he falls asleep, gradually move yourself (over nights in a row) out the door and around the door (so he can't see you). Pretty soon he just thinks you are around the corner and sleeps by himself.

Sleeping: Is you child in ababy crib or in a regular bed. If he is in a crib its time for a regular bed. If he is a regular bed try behavior modification by giving him a star .After 5 stars reward him with a toy, etc. The vomitus is probably undigested food.
