Re: "Appropriate" affection
I have an extremely outgoing 2.5 year old. He tries to kiss and hug strangers a lot. I just tell him "she/he doesn't want to hug, but I'll give you a hug" or something along those lines usually. We are working on it, he has absolutely no sense of personal space and I know other kids find it frightening and annoying. If he is being really pushy I give him a warning then we just leave.
