Far too many children are born to parents who, after the fact, wish they'd never had them. Raising a healthy child can be difficult enough but what if you have a child with special needs? How will you handle it when your life is turned upside down and it's not about you and what you want at all anymore? It's smart that you realize your fears. But if you're not 100% on becoming a mother, you owe it to your unborn child to spare them (and yourself) from any possible suffering, whether physical or emotional, because of your uncertainty or disappointment.
