This morning Ben was perusing through a week by week pregnancy book I have from the library. It's complete with illustrations and his analysis was quite entertaining.
When he came to a picture of the cells dividing, he said "mommy, do you have pancakes in your belly?"
When he came to a picture of a tiny tiny baby inside the womb, he said "Oh mommy, look at the little baaaaaby inside of you. (said in baby voice) How tiny is he? He's like a booger!"
After that, Ben asked me how big the baby is in my belly right now. I tried to explain that it's about the size of a large lemon (at least that's what the internet says) :-). He insisted that no, our baby was not a lemon. I then explained that it was about the size of my fist (this is how my pregnancy book describes 14 weeks). He then grew adamant and said "No mommy, the baby is not a lemon and it's not a fish! It's just a baby!) So there you have it!
