I'm leaving for my ultrasound this morning. My three-year-old has to accompany me, as I don't have babysitting available. Let's hope being in the exam room with me (albeit behind the curtain) won't scar him psychologically! I tried to explain how the ultrasound will let us take a peek at the baby. He seemed a little concerned that we would be hurting the baby, so I told him it was only an image of the baby made by waves. "Oh," he said. "Like light waves, right? We will shoot them at the baby and they will bounce back, giving us a picture without ever touching the baby."
Um, yes. So much for my preschool explanation. He's been watching a video of Beekman's World this week while I doze through first trimester. One of the experiments involves making a camera obscura--a cardboard box with a pinhole that reflects an image through light waves. It amazes me that he can already make these kinds of connections between something he saw on TV and a real-world phenomenon. I am reminded, yet again, not to dumb things down. And I think I can finally quit complaining about the gas for our weekly trips to the science museum!
