I have a daughter with a Rare Lung Disease. It's not a Terminal condition, but there is not a lot known about it either. They don't believe it is Hereditary but there are a handful of siblings that have been diagnosed with it so it is possible to have 2 kids with the same disease. They believe it is a spontaneous mutation, but I have my doubts. We are expecting #2 and praying for a healthy baby this go round, but like so many have said God knows what we can handle and if we are blessed with another special needs child then we will learn to handle it. I am still trying to figure out how I am going to carry oxygen and a newborn and wrangle a toddler, much less if the newborn needs oxygen too! but we will manage and hopefully sooner than Later Alida will be coming off her oxygen(probably not for another 3 years but I can hope!). Good Luck everyone! And yes I am worried, but I will handle whatever God chooses to give me.
