I think its fair to say that a lot of people in this thread agree with that.
We can't control what others do or say, but we can make ourselves stronger. You can take peoples comments and do either of the following: 1) Listen to it, and take it into account and if you still stand firmly by your choices, come up with a reason why you believe it is not right for your child, so that you are ready for another one of those comments. 2) Blatantly ignore it.
