Very FRUSTRATING!

So, I think this post will be me venting... about Brady!

I absolutely love my little boy to death. I love it that when he is ready to go to bed, he comes and cuddles with me. I love that when that he is growing up so much and learning new things everyday. I love that when in the middle of the night, if he is having a nightmare and crying for awhile, I can go into his room and comfort him. I love my Brady!

Now.... the time to vent.... Brady has become such an independent little boy. When it is time to eat, he knows that he needs to have his highchair and he stands next to it until I get it for him. He doesn't like for us to feed him. He will only eat when we do the airplane, but it gets old at every bite. Brady wants to feed himself. He is now at the point where he takes a couple of bites and then likes to throw the rest of his food. SO AGGRAVATING!!!! In the mornings I have to get ready for work, so I stick him in the living room in his highchair and put on a movie so that he intertained. Boy, does it push my buttons when I come into the living room to find the bowl on the floor turned upside down and pieces of food thrown all over. It does frustrate me also that since he wants to throw his food on the floor, he gets put in timeout and then doesn't get anything until snack time. So, the frustrating part is that he hardly ever eats. No, he doesn't cry because he is hungry, but still... He really knows how to push my buttons and I have to sit there for a second to calm down so I don't raise my voice at him. This can only go on for so long. Help!!!!!
Has anybody been in this situation? What did you do to overcome?
