Reading about insects not having backbones:
Laura:...Insects are invertebrates, but we have backbones so we are vertebrates.
S: Tigey is an invertebrate.
Laura: Well, I don't know. That's an interesting question. Tigers have backbones, so they're vertebrates, but Tigey doesn't have a backbone.
S: It doesn't have a backbone because it's a stuffed animal.
Right. Sophia often needs to remind us that Tigey isn't real...
