I've been saying that for years, too.
Preferably something like a separate cabin back toward the tail. Put a bulkhead with a locking door between the brat section and the rest of the plane. No access between sections except in emergencies or to board and deplane. (Because you know the moos & duhs would try to baby stalk the adult passengers during the flight.)
Then put bomb bay doors under the brat section so the crew could jettison the whole lot of 'em if they made so much noise that they could be heard in the forward areas.
