Aah! I thought about it, a lot and I am still confused if I can answer in a yes or no
First if all, lets consider that the woman can keep her children safe and provide them an average standard of living..
Then, why not? She should go ahead and give birth to the child . No harm even if it means that the next kid might bee dumb or deaf. She should either have thought about it before conceiving.
If she cannot afford to keep the child, it would be unfair to the other kids. Even though she should have thought of it before conceiving but now she isn't left with choices but to kill the baby in her womb.
Like my sweetheart mentiones, I don't have time and done point that I made might not seem clear. Please ask me in that case :)
