If your Nanna says she can tell you the sex of your baby from the shape of your bump, don't be fooled.
The old wive's tale says that if your bump is high up and pointing forward, it's going to be a boy. If you're carrying lower down and putting on lots of weight elsewhere then it's going to be a girl.
There is no scientific evidence to prove that the shape of your bump has anything to do with the sex of your baby.
The shape of your bump is related to your body shape and muscle tone.
Women with tighter abdominal and uterine muscles tend to have a higher baby bump whereas older women with comparatively weaker muscles tend to have a lower bump. Women with shorter torsos tend to have a wider bump, as there is not much room for the uterus to expand.
Naturally people are keen to talk to you about your pregnancy and speculating on whether you're carrying a boy or a girl is just Nanna's way of getting involved. Graciously accept the hand knitted blue booties she's made but don't promise to name baby after Grandad just yet...
