how many?

Over the weekend, Christie Padovani appears to have drowned her 7-month old daughter. I dare any parent to read the last paragraph of that story and not die a little bit yourself. Hell, I dare any person, parent or no.

By all accounts, Padovani was doing the best she could to monitor her own health and ask for what she needed. There are no good answers here and no one to blame. Still -- how many will it take?
