Since many troll posts had to be deleted, this
question sadly has 0 answers. I had a look at it, but can't really find an edit to suggest. The only improvement that comes to my mind at the moment is to get rid of [tag: behavior] and add [tag: discipline] instead, since the OP wants her toddler to stop the behavior, not understand it ("what's the best way for me to respond to being hit?").
