Raising a 2 Year Old

   DISCIPLINE

Hints? Tips? Tricks?...ANYONE?

     I have a beautiful 2 year old girl. She is my world and I love every minute I spend with her. She loves learning...she knew her alphabet, numbers 1-12, shapes, and colors at 18 months without a whole lot of instruction, she just picked it up. She loves showing off for anyone who will listen. She makes me smile more than I have ever smiled, and that is saying a lot, because I was nicknamed "Smiley Sally" or "Smiles" in grade school. I am blessed to have her in my life and like most mothers think of their children, I think she is perfect.
   However, as a firsst time mom, I am not sure what to expect. I read a lot of literature and I feel bombarded by information, on what to do, what not to do, etc. She is almost 2 1/2 and she is just starting to get very very sassy. I knew this day would come...everyone warned me about it, but I didn't know how I would handle it. I've handled it quite well, I think, she has gotten barked at, but most the time all it takes is a look and I get an "I'm Sorry Mommy....mmmmuah (kiss)!" Now, how long is this really going to last. I know she is going to continue pushing the envelope and trying to see what she can and can't get away with. We have tried a time out a few times, and it has worked for the most part. I have not really had to deal with punishing her too much, because she has been so well behaved, but recently...it was like a MONSTER woke up inside of her. It could be the cold too...we are all suffering right now!
     My question today is...what has worked for you? What have you found to be your successes and your failures? My daughter is starting to be bossy. She yells "NO!" when she doesn't want to do something, has even kicked during changes, and has just gone from this cooperative little girl, to this bossy rebellious little girl.
