A lady I used to nanny for years ago once told me about a book that she read which helped her to have a girl and said that it also helped at least 10 of her friends to have a child of the gender they were hoping for but, for the life of me, I can't remember what the name of the book was! We have a little girl and we really want the next to be a boy because hubby only wants to have 2 kids total. I know the gender of the embryo is basically a 50/50 chance depending on if the sperm that fertilizes carried an X or a Y chromosome but figured it doesn't hurt to try. Any help would be greatly appreciated!
