Trying to figure out...

I'm trying to figure out what is going with my daughter. She has been so feisty lately. She fights everything with so much intensity. I'm worry that I am setting her up for disaster, but I try to be the best parent I can be. I just wish that I understood why she is acting like this. I know that some of it has to do with being a 2 year old and all that development stuff. But, she is WAY more stubborn than other children I know.
