I think it can be early as 5. My grandson who will be turning 5 is interested in anything that helps you. He always asks if he can Windex windows, vacuum and wash dishes and rake leaves. (I double check the dishes, lol) He knows all his colors, the alphabet and has a great memory. He has my codes memorized for my phone and the tablet. He loves to cook too. I could teach him about laundry❗
My five year loves helping me cook too. I know my oldest is 7 and he helps with the laundry .
