My ds (almost 4, ASD) has been getting very fussy with his food so I decided to serve him what I was eating and if he didn't eat it then he was to go without until his next meal.
I thought it was going quite well, no more tantrums at the sight if something new, an occasional taste etc until I caught him.
He had managed to get the biscuit tin off the high shelf where I had hiddden it and was working his way through a packet of bourbons!!!
I think it is time for more cupboard locks methinks!!
