I have finally got an reward chart that works for us. It is a hand me down from my sister for my niece she gotten 7 years ago. It is a felt chart with a area to put in the chores. And it had the things we are struggling with the most. e.g. Say please/ Thank you, Eat all your food (its a constant battle with my diva to eat coz she is so picky) and a few others.You then choose a target amount of stars she has to get for that week. and she can choose her reward for the end of the week.Last week was pizza and this week is movie afternoon where she can choose any movie and we will make popcorn and have a whole cinema experience. in future if there is a movie on cinema she wants to watch we will do the whole movie and popcorn at the cinema.
Then she just have to add the stars for each chore per day. All the felt stick ons has velcro on them for extra stick.Then at the end of the week. the stars are tallied and if she reached target then she gets her reward.
