Conversation in my house this morning:
Avery: "Can I watch a Dora? Can I watch a Dora? Can I watch a Dora?"
Me (patiently): "Avery, television is a treat. It is something you can watch once in a while, but not every day. It's like a cookie...a cookie is a treat that you can have once in a while, but you can't have one every day. Think of it like that."
Avery (after pausing, to apparently process my brilliant analogy): "Can I have a cookie?"
