This is our journey to a baby brother or sister for Charlie. We have a lot to consider: a 25 percent chance of Meckel-Gruber Syndrome - a genetic condition which is uniformly fatal AND a 10 percent chance of Hypoplastic Left Heart Syndrome. But just because we know the odds of the worst happening, doesn't mean we aren't hoping for the best.
Charlie would love a sibling - even if he only gets to keep them for a very short time.
