Have you ever asked about your mother's diet/what/how she ate before conceiving you?
I asked my mother this last night out of curiousity (as I am her only girl and she had three sons.)
She sat and thought about it a moment, and then said, "Oh, that's right... I had been trying to diet and was skipping meals and mainly living off slim fast. I had lost a lot of weight before I got pregnant with you. We weren't really trying yet at the time to have a baby and then there you were! Shocked I had a girl."
And I went, "MOM! That's crazy!" Hah--I began telling her all of the things I have been reading and told her it sort of makes since why all of a sudden she had "her girl" because she had lost a lot of weight and wasn't eating well to try to keep losing weight. She was very intrigued by it all, to say the least.
To me, this just made a whole lot of sense with the theories of gender swaying.
Have you ever asked your mother's what their eating habits were before you were conceived?
