Baby in the ribs!

Where is it written that a baby growing inside of you has full reign over your entire abdomen? Silly baby, my ribs are a no-no! Do you know how much that makes my back hurt when you do that? Probably not! You are far too concerned with doing flips and kicks and learning how to be the up-and-coming Jackie Chan. When Mommy cannot breathe you need to move down in the belly. I know that there is not much room there, but please, help a Mama out!
