Dream those stories are just so sad. As Purple says I think sometimes people say 'silly' things, or things they've not thought through properly in an attempt to be 'sympathetic' or to lessen the pain, but realistically there is nothing that anyone could say that would lessen the pain of losing any child.
It's not quite the same, but I can't watch anything where a child is hurt etc without crying since having ds as I just can't deal with the thought of anything happening to him.
And Too, it's so sad that you (and all the others in your position) know all this from your own experience. I desperately hope that in March you'll be holding this gorgeous bean in your arms watching her scream her lungs out! And your dd is watching over you I'm sure to make sure this happens. This bean will always have her gorgeous big sister watching over her.
Sorry, I'm sure I intended this to be an upbeat post. And I'm hoping that I've not fallen into my own trap and said stupid insensitive things 
We are all Brooking. No. Argument. And we will be doing so all the way through. We will all get there and this time next year we'll be comparing pooey nappy stories, and sling success stories
