1. There are no rules.
2. Grab the camera first, ask questions later.
3. Keep notes with pictures to prove you had fun when they are older and are convinced they had a horrible upbringing.
4. Let them watch some TV. How else will they learn the word "hate" and "stupid"?!
5. Share them. "Oh, I'd love to watch your kids someday!" "Ok, how about Saturday night?"
6. Coffee (or wine. It's not my thing, but go for it)
7. Let someone else take them to Chucky Cheese.
