It's precisely because of situations like you described with your son and your wife during/after delivery and in NICU, and because of Themselves, that Mrs. SP gets extra points in the final decision. Not because she merits them necessarily, and if there was abuse it might negate all of that--but because in giving Mrs. SP that handicap (think golf here, not wheelchairs), you're acknowledging that there's another entity involved here.
As in my previous to @aliveandkicking, my instinctive reaction is to agree with you, hoosiermama.
But that doesn't mean I don't find it Immensely Irritating that, yet again, Left-Behind has to do That Which Walkaway Wouldn't.
Because obviously there was no such handicap where MR. SP was concerned.... "Too little, too late."
