Q: Is your belly a football shape? Or the shape of a baseball? Can you really predict the sex of baby based on shape of your belly or is that a myth? 

A: It's a common myth. The tale says that you can predict the sex of your baby based on the following shapes of your belly:

Football = Girl
Baseball = Boy
Round = Girl
Sticking out = Boy

The fact is that this is not true, and while it may be fun to guess, there is no scientific proof that the shape of your belly can determine the sex of your baby.
