Baby-Tossing: New Olympic sport?

Apparently in India, it is considered beneficial to an infant's health and future prosperity to drop them off a 50-foot rooftop.  My only question is, who came up with this tradition?  It's kind of one of those things like who decided to drink milk from a cow for the first time?  Anyway, the good news is none of the babies have died yet (although, I'm sure the record-keeping process on these sorts of things may leave something to be desired).  [warning:  if dropping babies off of rooftops bothers you you might not want to watch this]



edit:  scratch that last part
