My kids are 2, 4 and 6. At the moment they don't help at all in the house really, except helping to tidy their toys when you can't see the carpet in the playroom a couple of times a week.
When did your kids start doing chores? Did you have a formal rota or a general "everyone pitch in as required" approach? Any advice on which chores to give to young DCs, and how to make it run smoothly rather than become a battle?
