Family puzzle

Sadly, we live far away from both sets of grandparents, so we're always looking for ways of instilling an understanding of family in our daughter. It seems to me that this Grandma and Grandpa puzzle might be one way of doing that.

It's an interesting product: I've never before seen a puzzle in which the pieces are laid on top of one another like this; I suppose that would also help with the skills required for plotting things in three dimensions.

The five layers depict the a growing boy and girl from babyhood to old age, providing a nice representation of how each generation comes from the one before it. If you're brave, you might also use it to introduce the subject of where babies come from... fortunately for me, that one is a few years ahead of us yet.
