DS1 (6 1/2yrs old) has again (and I must stress again as he's done it before and we thought he'd stopped) taking food from the kitchen that he knows isn't his.
Today he opened a packet of crisps - took a few and left the packet so it looked like it hadn't be touched. He knew they were crisps I'd bought for myself as only 1/2hr before he'd asked me who they were for.
Yesterday I went to get one of my Twix bars out the cupboard and discovered they were all gone - thought I must have finished them and not realised, but when I asked him today he admitted he'd taken those, and also biscuits out the biscuit tin without asking.
He knows when he gets in from school if he wants something to eat he only has to ask, and I usually give both the DS's 2 biscuits when he gets in and have in the past made him a sandwich to keep him going until dinner time.
How would you deal with it???
