I am so sorry for your loss.
I am not sure if this will help, but in Peggy Vincent's book Baby Catcher she cites a story that I really liked:
It says that the babies in our hearts are like angels over our heads. Each of those babies take a turn when we get pregnant to be the soul of that child, but if one of those pregnancies does not last, the angel flies back up to be with the others until it's time for the next pregnancy, and the other little angels let it go first.
I hope you feel all of our prayers and love.
