Can a child in the womb kick often/hard enough to injure the mother?

[Answered on Quora.com by Tori Walker]

Oh my goodness yes! My first baby fractured 2 of my ribs. He had just lined himself up perfectly to push and kick with all his might straight at my ribs. Yeah ... and since it was the third trimester, no advil for me. Just Tylenol at low doses and a wrapping for my ribs. That was a very painful last 2 months of pregnancy.
