Just started chores with my 4.5 year old. She gets an allowance of $2.50 a week and is saving up for sparkly shoes. She feeds the dog, helps pick clothes and toys, help to set and clear the table etc. We decided to pay her for her chores so that we could also use this a time to teach her about the value of money, how it is earned by hard work and how we have to save it to get what we want vs. immediate gratification. It has been a very positive experience for her. It is great for her self esteem and it is a great way for us to give her positive feedback. I don't nag her about chores but I do remind her that she will not get her allowance if she doesn't do them and that usually works.
