KAM, I am deeply sorry for the sorrow that you and your husband are feeling.
I to understand what it's like to not only lose 1 child but 2, as I lost my baby twins in Aug 08, they were born stillborn at 19w 6d one of each a girl then boy.
I can only offer this advice to you, take it minute by minute, hour by hour & then day by day. You will feel extremley angry for a long period of time, vent it out, once you can do this you are releasing the massive build up of hate etc.
It has been 6mths since the passing of my angel's, and to honour them in my own way I am getting a tatoo near my ankle a footprint of each child , it mean's every step I take they take with me.
Please PM (private message) me you need to talk whatever you need, all us girls Bellybelly can understand what you are going through, you are not alone just remember that.

Take care
