I learned today that a witch toddler will accidentally make their toys disappear when playing with them. This only seemed to work on the toys that came out of the toy box and not her teddy bear. I know that werewolf toddlers can howl at the moon and scratch at the furniture. Fairy toddlers can use the fairy homes like their parents.
A werewolf child can transform and practice hunting. However, I haven't found any child interactions for a witch. Does anyone know any other than using a broom?
