I used to believe that if a pregnant woman had a bump out the front she would have only one child. Twins meant bumps out both sides. Side bumps and a front bump was going to be triplets. Quads would have been very uncomfortable with bumps in four directions. More than 4 bumps (babies) I couldn't even begin to think about.
