The Kata's

All tripp and gentry do is fight. I feel like a referee all day long. Every. Single. Day. Gentry is actually the instigator... she goes and purposely takes one of Tripp's toys that he is playing with and runs away with it laughing. While this is quite humerous to her (and me), he freaks out. Then comes that pushing, shoving, biting, etc. I am not sure how to handle the fighting. Tripp screams and cries at the drop of a hat if things don't go his way. Gentry just turns and does something else that she's not supposed to do, like throw something and stare at you. I have tried time outs, taking toys away, etc. I don't know what to do!
Today Tripp had an absolute meltdown at the baseball game. GG, Tripp and I were waiting for the game to end so that we could go on the field and run the bases and play with Matthew. Well, the game had one out to go and the other team decided to tie it up in the 9th. Tripp got tired of waiting and began screaming his eyes out. I just sat there trying to calm him down while Gentry was taunting him beside me. We were being stared at, although I could've given a crap, and Matt even could hear him all the way out at 2nd base. I finally got up and took him home telling him he could not play with daddy on the field anymore. Gentry stayed with Lauren and came home later on. Then I felt bad, cause he was really excited with his bat and balls to play. I need someone to tell me how to discipline!
I also need someone to tell me how both of my 2 year olds can skip their nap and still not go to sleep until 9pm. WTF? They are the energizer bunny times two.
I am exhausted...... when will the fighting stop?
