Do you know any one (or any couple) that has thought this? I imagine the odds of having a child with a physical or mental disability are quite small, but the chance is there. Having a child with a disability must be rewarding and very challenging. I suspect there is a lot of emotion and financial stress on the parents (and siblings), along with the stressors on the disabled child. Do you know anyone who decided not to have kids for this reason? Sounds crazy, I know.
