@mrsmord, lol yeah that's what I've been reading. A lot of the moms would bought that book said they did everything the book said and they got the baby they wanted everytime.
it took me a year and a half to get pregnant, I couldn't imagine how long it wouldve taken if I tried to make specific conditions lol!!! but I don't think it's fail proof anyways, I was looking at the things in your last comment and a lot of it doesn't make sense. I eat all kinds of fruit (acidic... but it's hard to find food that isnt acidic anyways) have an orgasm every time we'd have sex, and I ovulated at the end of my period which is when we had sex.... and I had a girl lol!! I truly believe it's just a 50/50 chance unless you go into a lab and have them do the thing where the spin the sperm and then artificially inseminate.
For a girl, you would make your diet acidic, no orgasm, have sex with your partner on top of you, have sex 2-4days before you ovulate. For a boy you make your diet alkaline, and have sex near or on the day you ovulate. @mrs.medrano @mrsmord
The girl sperm are slower, live longer and the boys are smaller, faster. It's about the timing and your diet. Girls can survive in acidic environment and the boys in alkaline environment.
