    Does this mean we already know the gender of the new royal baby?

    A scarily accurate birth predictor, that guessed the gender of both George and Charlotte correctly, might have let the royal secret slip

    From the editors of Good To Know

    By Rachael Martin

    The Duke and Duchess of Cambridge, who announced that Kate was pregnant with her third child back in September, and recently revealed that her due date is April next year, have kept characteristically tight-lipped about whether or not they know the gender of the baby yet.

    The royal couple didn’t reveal the gender of either Prince George or Princess Charlotte before they were born, and it’s not officially known whether the couple have chosen to keep the gender a surprise for themselves too, or have found out before the birth in secret.

    However, amidst all of the speculation surrounding the new royal baby’s gender and whether or not the couple know what they are expecting by now, it seems that this simple Chinese birth predictor may have been holding the answer to the question all along.

    The ancient Chinese birth chart, which is supposedly based on the Chinese Lunar Calendar, uses the mother’s age and month of conception to predict what gender the baby will be.

    An ancient method of predicting a baby’s gender, it isn’t grounded in science, but it is eerily accurate…

    Mums-to-be simply use the Chinese birth predictor grid to match the age they will be when they give birth and the month they conceived, and then whichever square joins the two columns is the predicted gender of their baby.

    Based on the age Kate was when she gave birth, and the average duration of a pregnancy lasting roughly 40 weeks, the Chinese Birth Predictor correctly guessed the gender of both Prince George AND Princess Charlotte before they born.

    So, based on the ancient formula, what is the gender of the new royal baby?

    Well, that would mean the gender of Kate’s baby is…a GIRL! If the Chinese Birth Predictor is correct, then Prince George and Princess Charlotte will be joined by a new little sister next April, and the royals will be welcoming a new Princess into the family.

    We can’t wait to see the first pictures of the little one (and to find out if the birth predictor will be right for a third time...)
