They are horrible, the never help clean up the mess they made and even gotten into my room now and took things out of my room! I'm so irritated and even flipped out on the 7 year old tonight because he was angry and flung a blanket and it hit me in the face. I'm 28 weeks pregnant, and shouldn't have gotten on to him (also has a  two year old brother) but between that and him and my 5 year old little girl arguing the whole night I just lost it. (She got yelled at also). My daughter knows how to respect people's things at their house and the right way to act, but when they get together it's terrible. If it's not one tattling it's the other! I'm so over it!
