Tonight, I sat down with the kids and we flipped through the album. We passed several nursing photos without any comment. However, we got to one where the twins were tandem. And Norah stopped my page flipping and says, "what's THAT?!" and Aidan started giggling. I said, "you don't know what that is?" Norah said, "No. What is it?" Aidan said, "they're sucking your KNEES!" [giggle giggle]. I said, ''noooo." This is when daddy chimed in and informed them that they were nursing from mama ... that's how babies get milk. And Norah says, "gross!" (wth?!) and I said, "that's not gross. that's life." Aidan says, "yeah. like a cow. they're on your nipples just like a cow!"
