I agree Alec. Lies don't hack it with me. Why lie when the truth is called for.
Simple enough to talk to the Child and attempt to explain he is in an enviroment where Folk are sick so it is a place where he might want to be a little calmer (use whatever word works)..but...he is a child and I don't know about anyone else but Hospitals are, energy wise, un-nerving places to me anyway and children pick that up. Sounds to me as if this wee bored boy was being.........a wee boy!
Creating a bad boggy Nurse with Sticks and threatening the loss of material things in attempt to "control" is...pathetic.
Yet another grown up with a lot of growing up to do!
