One of them is OMSI. There's a "Life Science" exhibit there which includes diagrams of inner body parts, reproductive organs included. They have a whole display of babies at different stages of fetal development (which creeped me out when I discovered that they were actual preserved pre-1940s babies and not just replicas). I kind of hurried the kids past the part with the reproductive organs that looked like it might go into some details about conception (albeit with scientific language that goes way over the kids' head).
The second thing that has me thinking is Kyrie's First Communion classes. I'm trying to do some Religion Lessons in our homeschooling now and then to make sure she understands the prayers she has to memorize and the topics they talk about (as well as introducing Elijah to it). We discussed the 10 Commandments... and when she asked me what "Do not commit adultery" means, I was at a loss. I really want to discuss the Apostle's Creed with her too (that's one of the prayers she has to memorize); but it has the same issue, with its "conceived of the Virgin Mary".
The thing is, my instincts are very firmly of the opinion that I should just be straightforward about it and tell them, in basic terms, what sex is. I could then explain what adultery is as easily as explaining what murder is. I wouldn't have to worry about Science Exhibits. I could share with them the miracle that is the Virgin Birth in a simple but meaningful way.
But Kyrie and Elijah are only 6 and 8. First and second grade. That is, by the standards of everyone other than me, way too early for kids to know what sex is. Ken certainly thinks they shouldn't know, and I'll abide by his resistance. But I don't really get it. How can we think kids are old enough to learn the Apostle's Creed, but not old enough to understand all of it?
