I don't think most people have a clue what it's like to over-agonize about every single decision you have to make and have made about these kids. It's easy to think everything is clear cut and simple when you're not living it. I know I certainly had a lot of preconceived ideas about the things my kids are now going through and I'm ashamed to admit that I made snap judgements about people when I didn't know enough about their circumstances to begin with.
Personally I just have to remind myself that they simply aren't in my situation, and hope that they never have the misfortune to be (my kids have medical issues too).
