Natalie first with David nearby pretending not to listen:
- See this picture, it's a cross section of a woman's body. This is the vagina. This is the uterus. You have both these things inside of you. "Really?" Yes, This is your urethra, where you pee, this is your anus where you poop. Your vagina is in between. It connects to your uterus. Now this picture is what it looks like from the outside. (Note: pictures were anatomically correct illustrations, not photographs)
- I then explained fallopian tubes, ovaries, eggs, and heading down into the uterus. Then the uterine lining which then sheds if the egg is not fertilized. "How does an egg get fertilized?" There has to be sperm to fertilize an egg. This is what a sperm looks like. It comes from a man.
- David: "Wait, what?" Where does sperm come from? He rushed over to look at the book.
- This is a cross section of a man's body. This is the penis and these are the testicles. Do you know what those are? "Yes." Well, the sperm are created in the testicles and then go through the vas deferens and out the penis. "So I pee sperm?"
- No, this is your bladder, it connects to the penis as well, but when sperm come out the urethra is pinched off and you cannot pee and release sperm at the same time. "Oh, okay." What do sperm do?
- They fertilize a woman's egg and create a baby. "Wow! How?"
- This is an egg. Here is the sperm connecting with the egg. Then the egg attaches to the uterine wall. David: "Wall?" It just means the lining of the uterus, here, see? "Oh, okay." Then the egg and sperm grow and multiply like this. After nine months there's a baby like this. Here's the umbilical cord. That's where your belly button comes from. "That's awesome! How does our brain work?"
- We then moved on to that section of the book.
