When big babies make their way into the world, sometimes something has to give and in my son's case it was his collarbone. My lil guy's debut was a bit of a struggle. As all nine pounds and four ounces of him squeezed down the birth canal, he fractured his clavicle, which connects the sternum to the shoulder.

According to WebMD:
Occasionally during delivery of an otherwise healthy baby, the forces involved in trying to deliver the baby from the mother can break the collarbone. This is the most common bone broken during delivery. This is usually detected in the hospital, and the baby recovers well.
