I've been told a friend is given a baby bottle filler with very warn near hot prune juice. 2 ounces of Castor oil are mixed in and baby drinks it right down. If diaper doesn't get filled in a couple hours his legs are lifted and a fleet enema is squeezed into him. He is re-diapered and within a few minutes the diaper is full. It needs changing the rest of the day as the castor Oil starts working on him.
