Definitely agree with the others that you did fantastically well. I had this experience earlier this year and I was a basket case - poor newborn nearly drowned in my tears I think.

I think being pregnant again softens it, but nothing takes away from the fact that like you say, its a "this should have been" moment. We never forget our precious angel babes. My SIL has just passed her angel's due date and is not pregnant again yet. I worry for her, and worry how hard the impact of my baby being born will be for her.
