Rewards

We have starting doing a reward chart with cam to try and improve his behaviour. For the past couple of days he has been doing amazingly well and this puzzle was his treat for yesterday which both boys are loving. However cam's behaviour today has been horrendous and he didn't earn himself any stars.
We went to the park with Isaac and his mummy and cam must have hit ever child there and even pulled one boy's shorts down. God knows what has gotten in to him but it was mortifying. It seems like we take one step forward and two back.
We will keep trying to crack this with him but god it is demoralising.
Thank goodness ollie is as chilled as he is. He is a breathe of fresh air in a hurricane!
