We took care of 4 extra kids this weekend.  My 3 nephews and one niece. 
It sounds like a lot having 6 kids in the house but it actually wasn't that bad.
I thought it would be a lot more hectic then it was.
Don't get me wrong...it was hard, and we were constantly cleaning AND it ultimately helped us realize that our decision to only have 2 kids was a very smart thing to do....BUT it was fun to have all those little people running around. 
My nine year old nephew was a big help and all the kids (the rest of them are 5.5 years and younger!) LOVE him, so they just followed him around a lot. 

So, though I don't think we'll be planning a weekend like that any time soon, it was nice to know that we were able to do it and no one got hurt and, most importantly, everyone came out of the weekend alive! 

ps...they didn't sleep on the floor in the family room...we had just set up a movie....just didn't want you to think we were horrible people.
