re: Doubt this has happened to a TDer before.

Prayers for you and your wife. This may be a very difficult process for your wife. She may likely need counseling, as an event of this nature could become something from which she doesn't heal. She has lost a child, which is terrible enough, but she has little way to grieve and draw support (assuming very few know and she has no public connection to her child). I can't even imagine that first realization.
