Since becoming a mother, have your reactions to...?

I've always been very sensitive to children & their needs, but I do think I've become more outwardly emotional about it. I think before I was able to mask my emotions, now I'll hear something about child abuse/neglect/starvation & I can't hold back the tears. It's so real to me now, I can hear the stories and look at my daughter and just wonder how could someone do that. Recently, there was a baby found in a garbage can near where I live...I can't help but think of my daughter & it makes me tear up.
