Rules for my 2 boys (6 and 4):
No picking up the cats by the neck.
No throwing baseballs in the house.
No swinging bats in the house...or at each other's head.
Clean up your toys, unless you want them to be thrown away.
You're responsible for making your own bed everyday! (They really love making their beds)
Put the toilet seat down when you're done.
If you noticed that daddy left the toilet seat up, put the toilet seat down and you will be rewarded thusly.
Oh and the most important one:
If you're in the fridge, make sure to ask daddy if he needs a beer.
- Kidding...sort of.
Not too hard to live by, if you ask me.
