Sadness

I keep wondering when it won't bother me to hear Cameron ask when we'll be able to have a new baby. He's asked lots of times so you would think it wouldn't hit me like it does. However, it always comes out of nowhere. It breaks my heart to hear the words and see the sad look on his face when I tell him that it isn't up to us; that only God can decide if we get to have another baby. I feel like I'm letting him down every time I say it. :-(
