What's rule #1?

Rule #1 for Justin growing up was, manners. Rule #2 was, have fun! This simple and effective way to get kids to be polite will be central in our parenting. So far I'm extremely proud to say that Adelaide not only says "please" but "thank you" as well. When she is asking for something all I have to say is, "How do you ask?" or "What do you say?" and she comes back with the sweetest, most darling pleading "please" you have ever heard. Then she follows it up with a "thank you". So far it's my proudest achievement as a parent of a toddler. There is one problem though. Now that she knows "please" she uses it for things like watching TV or continuing a game that has been exhausted. When she says please it's almost impossible to say no to her and I think she's starting to pick up on that. At least we are starting on rule #1.
