All completely erroneous and irrelevant.
Once born, a baby cannot be murdered under the law for all of the reasons you cite above for which you would murder a pre-natal.
Again, you are simply appealing to the bias of ageism here, and that appeal is morally wrong.
You hide behind the skirt of law, when law has yet to catch up to the foundational facts of truth presented by science that unconjecturably presents the newly conceived as a person, a human being in that person's earliest age of life.
You commit here the bias of ageism, arguing that there are certain ages in a person's life where murdering them is okay.
I disagree ... and so does the overwhleming vast majority who are onotologically based, not utilitarian based, and who know the scientific facts of the matter.
I find your murder with appeal to ageism to be heinous in its irrationalized butchery.
