Ok, it's not buying a book thats worth mentioning, but the book I bought. We are going to try for one last baby and thought it would be nice to have a girl and Kaitlen really wants a sister soooo we'll give it a go and see if we can increase our chances of a girl. We'll be thrilled with either a boy or a girl, but it doesnt hurt to try. Ofcourse from what I read online about the book it's harder to get the girl. might explain why we have 3 boys. LOL, But the fun part is trying, eh?
