Yeah my dd is 8 and has been getting an alllowance (sporadically) for about a year. She has a list of requirements to meet to get it. This includes doing things, when asked, without arguing about it. ie. Put this in the trash, help mom set the table...etc.
If she misses three of the things or more that week she does not get an allowance. We give her 2 dollars a week. Be weary though...they talk about what they get for allowance, at school, and we have been asked for an increase many times. I refused each time because she doesn't do enough to earn it.
We worked on the list together, which helps. That way it isn't too much or too little.
Hope this helps.
