What should we do now?

Over the past two weeks, my two daughters who were both diagnosed with rare terminal illnesses were frozen through cryogenics. It has been heartbreaking losing both of my daughters. My wife is pregnant with our third child. Genetic testing has shown that the child has a 99.9% chance of having the same terminal illness in the first 10 years. The other thing is that if they don't find a cure for 100 years, my two daughters currently frozen would wake up and have no parents. Since my unborn child has a high chance for the disease as well, should my wife be frozen with my daughters so that way they have at least one parent when they get out? I would hate to lose my wife, but I would also hate for my two daughters to wake up in a world without their parents.
