He has cooked school lunch which includes a pudding and he always 'makes the most of it' iyswim.
He has martial arts on Thursdays and sometimes mondays too ahd I've been giving him sandwiches for 'dinner', with carrot sticks etc, same as I'd do for a lazy lunch (reasoning that his main meal was lunch). Other days we have cooked food obv.
My mother seems to think I am depriving him massively (despite our diet of boiled egg and soldiers for dinner, switching to ready meals when we hit our teens), but it seems ok to me?
He can have fruit or whatever as well and when he gets back from martial arts he'll have a yogurt or something.
