When my niece and nephew were young, I gave them tree ornaments every year starting with engraved ones for their first Christmas. Then my niece got possession of the doll house my uncle made for us girls when we were small. After that, I gave her things that could either/or/and be used in the doll house or go on the tree. They really appreciated them when they started out with their own trees to already have a supply of "special" ornaments.
