Some male and female animals look exactly the same... BUT the way the document is organized, you'll see a baby, mommy, and daddy of each animal. The paper size that I used was a long skinny sheet of paper. If this is not really ideal for anyone, please just comment. I can make a new document where they're on 8.5x11 (standard size sheet of paper).
I won't do that yet because, so far, they're just for us!
I printed these, cut them out, laminated them, then cut them again. And I have Alexander match the 3 animals to each other.
