I envy anyone who thinks this is a good idea - because it means they didn't have to grow up alongside a severely disabled relative.
At best it's an incredibly stressful burden, at worse it's like living with a waking nightmare which I wouldn't wish on anyone.
Its an extreme burden, and in many cases its inhumane imo. Some people say its selfish to abort, I would really counter how could you allow yourself to have your child not have a great quality of life out of the womb for many of the genetic disorders that could occur.
Just today heard of a woman grieving over their child who was born with half a heart and didnt survive surgery. Its absolutely insane to want some one to come to term and know that child has a low chance to even see their 1st birthday.
and you know what its not for them to decide whats best for a parent to do. Let parents decide that.
