I am pretty sure that the baby I'm carrying at the moment will be an only child. One of my close friends had leukaemia a few years ago, which made me think about what this baby would do if she didn't have any siblings who could possibly provide tissue/marrow matches.
Has anyone had the umbilical cord frozen and stored? I would love to hear from any medical researchers about whether it's a just a way to fleece paranoid parents, or if it could actually be useful to her one day.
