Last night, Bryce came upstairs and asked me what a "liner" was. Trying to get some bearing on what he was talking about, I asked him to tell me where he heard that. He explained that he had just seen a commercial with a long white thing shaped like an airplane and they said "maximum absorbency, but thin as a liner." Fun...sanitary napkins.
Josh gave him a quick explanation and Bryce went back downstairs to play. However, he was back upstairs in five minutes asking more questions. Of course, by then I was the one he was interested in talking to (how does Josh always manage to get out of these things?). Having been through several pregnancies with me, all the kids know a fair amount about sex and pregnancy, but we had never yet delved into female periods.
So, I pulled out the trusty Human Anatomy book that the kids all love to look at, we flipped to reproductive systems and had an impromptu lesson on reproduction and menstrual cycles. Not what I expected to be doing on a Tuesday night. Darn Olympics, without them we wouldn't even have the TV on in the evening!!!
Just kidding, we always try to take the time to help the kids understand whatever things they are interested in learning (to the degree that is age appropriate). When they have questions, we try to answer them. I still remember the day after we talked to Aubrey about how boys have a penis and girls have a vagina (age 2 1/2) when my parents came over and she proudly pronounced, "Grandma, girls have a vagina and boys have a penis...show her yours Daddy!!" He didn't, but we all laughed.
Aahh, the fun of parenthood. I am sure we have many more of these experiences to look forward to.
