As a teacher I would line up the students ( 5,6 year olds) up when transitioning to another place and "bob" them on the head.. (nicely) and sing a little bob song. The students thought it was funny and we enjoyed it daily. One morning a parent walks in and begins screaming and cursing at me. She said " My baby said you 'bobbed' her". After a meeting everything was cleared up, but I sure don't "bob" anymore. Honestly, I'm nervous to even touch the children, they are young and some children do need to have a lovely, appropriate touch but is it worth the risk?
I agree with this. Informing the parents before hand usually keeps things cleared up and if they have an issue they can contact you.
I like this solution. I think a high five would be better than "bobbing" the child on the head. I probably would be upset if i seen someone touch my childs head even in a song.
