Two vs Four

I've always thought-what could possibly be the difference in having two children vs. four children? Well today after having my sweet niece and nephew over night-I have come to realize a "few" things and here they are:

~If the house is quiet-something is wrong.
~Eating out DOES cost more than eating in (Right now we can buy one large value meal and share it!)
~You CAN lose a child (in seconds) when you THINK you KNEW where they are at. I've always wondered how a child could flat open the front door, walk out on the driveway, and find himself in the street. IT IS HARD TO KEEP TRACK!
~You'll go through a gallon of milk in ONE day not a WEEK.
~Your house will never been in "Martha Stewart" shape. In fact, your house is bound to be deemed "unlivable" at times (many times).
~First thing, purchase a dog (any dog)-they will clean up the things you thought you'd gotten off the floor months ago.
~Come to terms with the fact that you will have a "community" toothbrush and hairbrush. You'd be lucky to find the one you originally started out with.
~Purchase a COSTCO card. Boys get older and eat A LOT MORE!
