DS1 is always hungry

[IAmReallyFabNow]

He lifted his shirt yesterday and his stomach is so flat. He is thin but not skinny. He has just asked for cereal though to be fair they had an early tea. What is the best thing for him to eat for supper? He normally has something later than this but between 7-8pm. He is 9.

My DS2 has hollow legs, i'm sure. He's always ravenous and there's not a pick on him.

He usually has a big bowl of ready brek for supper maybe with some dried fruit chopped into it. Keeps him going til morning when he eats the hind leg of the lamb of god

DS had porridge.
