@eoe,
Or it must may be a young woman who let things get out of hand with somebody she loved and got pregnant. When my daughter was 17 I hoped she had sufficient information and good enough judgment to make good choices. But those choices were hers to make and I was no longer in a position to make them for her. I'm sure Sarah would have not wanted things to be the way they are and I'm sure she and her daughter would love to rewind the clock on that. But when you screw up, all you can do is the best that you can do with how it is.
(And no, my daughter did not get pregnant. I would hope that her family would have provided the love and support that Sarah's is providing if she had done so however.)
