My SIL took one look at our scan photo and is claiming that, because of the nub theory, she knows what the sex of our baby is!! Was literally the first thing she said when she saw it, which we weren't exactly expecting...
I've read a bit about it but I can't make heads nor tails of it... And I'm also not entirely sure how much to believe it any case, but meh, might be fun to do a guessing game too if she thinks she already knows (or "knows"). Any ideas anyone? Thanks
