Designer Babies

I think that "designer babies" is unnatural way to have a child. I think that the child will not live a normal life if it has to give its sibling whatever it needs; the child will be responsible for his/her sibling's life. That is a very large responsibility for anyone let alone a baby. I do understand why some parents would agree with this; if they were in their shoes and one of their children was dying they would do anything they could do too. Some parents on the other hand do not agree with this because they think it is basically torturing the baby and the baby will not have any control over its life.
