My DS1 is 16. Our house is 3 stories. On the bottom floor we have the living room and the downstairs toilet.
The first floor is the kitchen, Ds1s room and another toilet. The top floor has, mine and DPs room, DS2s room and the bathroom.
DS1s room is next to the kitchen and he always sneaks into the kitchen at night and makes himself cereal or he eats a packet of biscuits to himself. We don't realise until the morning as me and DP are either in bed or in the living room.
He eats a lot for dinner. This never used to be a problem as he used to share a room with DS2 but obviously now he's older he has his own room.
We've asked him not to eat the whole packet of biscuits as they're not ‘his’ and its unfair on DS2. At times he ate the rest of the cereal that's left and that means DS2 refuses to have breakfast (he's only eats one kind of cereal). But he just ignores us and carries on doing it.
He also doesn't clean up after himself, this morning I went in the kitchen and there was cereal all over the side, he didn't wash his dish up after he used it and he left the cereal out.
Any advice on how to stop this?
