Not A Mule
If nature was fair, mothers would have grown an extra arm each time they gave birth to a child. The responsibilities of a mom after a new baby comes to her world are never-ending and two hands aren’t enough to carry them all.
You would be carrying a grocery bag, a water bottle, a giant teddy, a milk bottle, and your child would still hand you a toy he doesn’t wanna play with anymore. On top of that, there is a stroller that you have to move while you walk. A couple of extra arms could do wonders.
