I agree with all the comments so far on this issue. I have a few two year old with these behaviours that I was looking for answers too on how to cope. I like how you have written a letter to the parents because sometimes all I think I do it chat with them about it when I really need something formally written to reference later.

I have a lot of problems with hitting here and just had all the families over for a BBQ last weekend. I see now where some of the kids get their behaviours from because one of my DCK's was acting up and the parent went over and hit her a couple times to correct it (not hard but just enough to make her know that he doesn't tolerate the behaviour). He did it right in front of me (SMART DAD) but now I realize where some of the behaviours come from.

I also liked the idea of pulling that article you mentioned and handing it to the parents so they can see another person's opinion.
