No, but if you have really helped raise other people's children (which is still different than having your own), you would know that it is IMPOSSIBLE to protect them from every potential danger in the world, let alone an accidents.
an accidents=accidents, sheesh!
REAL parents do their human best to watch over their children and then just pray to God that He will take care of those things that they cannot prevent. I guess old Chogokin won't be sleeping once he/she has a child because only God knows if SIDS et al. will take them while you are sleeping.
