I have started giving ds (2.3) a single chocolate button at the end of the day when daddy gets home if he is a good boy all day.
It seems to really work as e.g. when we went for our walk today and he started messing around (as he has started doing recently - trying to sit down on the ground etc when we are walking) I just said 'oh remember what I said about having to be sensible to get your choc button' and lo and behold every time he slipped back into it, he stopped and was then really good all day.
So I'm using it as a bit of a threat 'stop x or you won't get your button'.
I'm sure I've seen somewhere that you shouldn't really use food as a reward but this is just one little chocolate button so does that matter if it is working so well?
Generally he is a very good eater of fruit and veg and would pass over chocolate for fruit a lot of the time, so I don't have any concerns there but maybe there is a drawback something I haven't considered?
