Why must they fight?

Why oh why must my children fight, whine and cry? From the second that my oldest gets home from school the fighting begins. The whining if all day long with my middle and then when my oldest gets home from school she begins to whine and cry. I feel like I might lose my mind with all of this nonsense going on. To top that off my youngest went to his well baby check up today for me to find out that I forgot to take him to his 6 month well baby check up. So my poor sweet baby had to get SEVEN shots :( talk about feeling like total crap. So now he's super fussy b/c his legs hurt.

Today hasn't been the greatest day. But I'm happy and thankful to have each and everyone one of my children.
