Hi All Does any one have experience with the Nub Theory? I have posted my scans on FB Groups and also paid £10 to the nub Techs. All say boy so I'm guessing I'm having another little boy. But is it accurate? Can I assume I am having a baby boy from this or is it just a total guess? I've already bought a few blue cardigans as the accuracy rate on the website etc is super high! Lol. The baby does have a super "boy" nub from other photos I've seen. Anyone used them and they have been correct or incorrect for you?? Thanks!
