Ok, no Emu. In fact, check out the great post that my friend Annalia put on her blog: HERE.
Instead I'm going with Otter. Owl and Otter. Here's why:
Otters are cute and playful. Like my baby E.
They like the water. Like baby E.
They have cute little faces, and my baby E sometimes has a little otter face, but even when she doesn't it's still a cute little face.
That's all that I know of Otters, so that's all the similarities that I can find. But it's good enough for me.
