Realm Of Magic was released a while ago and it sucks that though children can be spellcasters they can not practice magic!
But FerdianaSims has made a mod for just that!
The mod "Children Can Spell" gives children the ability to not only cast spells, but use the cauldron, conjure potions, and participate in magical duels!
This mod and many others that expand the capabilities of children in your game can be found on Tumblr!
