Self trained through many years of experience, we are 2 mothers with a passion for the Nub Theory. Our love for learning the art of early fetal sex determination began during our own pregnancies. We discovered and began to learn everything about the Genital Tubercle (nub) and its stages of development. It was then, we realized that the nub theory was far more accurate than the traditional potty shot and began to use that was a more trusted method of confirmation. Throughout the years of our training, We became a trusted source of nub theory predictions for many in our personal lives. We loved doing it so much, we started doing it for a living!
