Emma's always been a precise, clean eater (FILs genes to thank for this, she eats JUST like him and has his little, tiny mouth as well so its partly to blame). Never had to teach her to keep her chin over the plate ;-)
Oscar eats like an animal and has a big gob that he refuses to do anything other than stuff as fast as he can with what he actually WANTS to eat - forget the rest - and he used to be very, very messy. But now he's 5 the mess is contained to face and chin, almost ;-)
