I just question the WHY since at no time in her post did she mention she really want to work with children, that she has a passion to be with children, that she feels she will happier with children than in her current career or anything to that sort.

SLM you mention knowing it was your dream that you wanted to work with children. in which case way to go with making the leap. I am curious as to why the OP is deciding to do it. Her post didn't really say.
