Good luck with your book. You are doing a great thing. I just found out that a friend's son and DIL just lost $20,000 on a failed adoption with no recourse. They did a few failed ivf cycles and had miscarriages. They told her it was her eggs. They decided to go to adoption thinking it was a more sure thing. Now they are devastated and out of money. They're are looking into donor embryo though. But first they need to grieve the loss of the adoption.
I know I put myself in a bad financial position in order to have ds. And there is no way I could afford more. But oh so worth it.
