Terrible Two's??!!

Emerson is changing so much every day. Most of the time the changes I see in her are so amazing. She is talking more, signing more, and walking more easily. Some changes are also occurring that are so cute, but I realize that they are WS related and will need to be worked on sooner rather than later. A big change that I've seen in her is the extreme social behavior. She is afraid of no one and everyone is her best friend. Examples that I've seen lately; walking up to a shoe sales woman who was kneeling on the floor, touching her arm, crouching so they are face to face and saying, "hi, hi, hi, hi!"; going up to a strange man and holding out her arms and saying, "up!". While this is completely adorable now and she gets all kinds of positive feedback, I've decided that I need to start setting expectation right away. I've tried to think of what is appropriate and what will work long term. I think I'm going to try and let her just say "hi" to people. No touching, no high-fives, no blow kisses, just one single "hi". I think about all of these other ways to greet people, but in a few short years they will be very inappropriate with strangers. I know that she is only two, but this oversocial behavior has come on so strong and literally happened overnight. She has no fear and loves everyone. I've seen her try and kiss strangers. Any advise from the moms with older kids would be very much appreciated.

Another big change in Emerson is the new two year old attitude. She is getting into so much trouble lately. She eats Newman's dog food, dumps his water out, plays in the toilet, drops toys in the toilet, trys to flush them down, opens our entertainment center and empties it, steals towels and walks around with them on her head. Yes, she is a complete goof ball. When I tell her "NOOO!", she now has a tantrum with throwing herself around on the floor, turning red, screaming, and growling at us. She has also put her mouth on me a few times as if to bite me, but thankfully, chose otherwise.
