I have been rewarding my 3.5 year old DS with chocolate when he is well behaved at nursery, until recently he tended to only get a good report a couple of days a week so that was 2 treats a week (small packet of buttons or freddo bar). Recently his behaviour has been excellent so I am having to reward him every day but is that too much chocolate? If he has this I don't also give cake/biscuits at home, just fruit/yoghurt. I want to encourage this good behaviour by rewarding him but don't want to be in the habit of having chocolate every day
