I wouldn't worry about her, Habitual Quitter. The others are right; you did only what
you could to protect your own home environment, and it was her responsibility to see
to it that her children were properly cared for. Most mothers wouldn't even think about
going on a trip with their child ill.

If I were in your shoes, I'd be happy that she didn't call again until she had grown up
a good bit and learned how to behave as an adult. Please don't "enable" her to keep
doing these things.

Stand strong and firm in your truth and your concern for the little child. Let her
see the error of her way in mothering. That may make her grow a good bit.

Peace to you; you deserve it, in my view.
