We don't couple it to chores. Chores are something everyone does because it helps the family. We're trying to be intentional about not connecting those concepts.

I think we started "chores" when she was 3. Obviously a three year old doesn't really do much, but she showed interest in feeding the dog and folding some blankets so those became her chores. We make a point of having both parents visibly do chores together.

We'll see how effective this is in another ten years, I suppose.
