I meant at what point is it no longer ok to kill a baby?
Don't accuse me of dodging the question when I answered the question you asked and not the question you meant to ask. Write clearly and read what is actually written, please.
When a doctor should intervene to end a pregnancy is a matter for medical regulators to decide. I've taken on board several PPs' point that doctors don't like carrying out late terminations and shouldn't be forced to. Whether foetal euthanasia is used would also be a matter of regulation. My focus here is on bodily sovereignty and criminal law.
A woman should be able to do something to her body that will, potentially lethally, affect the baby that she's pregnant with at any time without risking criminal prosecution. This doesn't give her the right to smother the baby on its way out or in any other way directly harm the child. I am talking about her body.
And as for life support system, this baby didn't need life support. It was going to be born whatever happened, and it was born. The only thing in question was would someone kill it before it was born or not. So by your own logic this was murder because it had no need of life support.
I didn't talk about needing life support. I talked about using her for life support. Again, please read what I actually wrote.
The woman took some tablets by putting them into her body. Those tablets had a lethal adverse impact on her baby. She put the tablets into her body, she should not be criminalised because it was her body.
Some women drink or smoke during pregnancy. Some smoke on purpose to keep the birth weight down in the hope of an easier labour. They know that they are risking the baby's life and health. If they miscarry, should they be prosecuted?
The Pregnancy and TTC boards are full of women worried about eating nuts, shellfish, blue cheese, and even coffee during pregnancy. Do you like the idea of women being criminalised for having a miscarriage because she drank six cups of coffee per day? Or after eating oysters and a champagne toast at her brother's wedding? Those things are known, or at least suspected, of endangering the baby. At what point do we stop criminalising what women do with their own bodies during pregnancy? I say that we shouldn't criminalise them at all.
Laws that criminalise what women do with their bodies during pregnancy result in women being criminally investigated and jailed after miscarriage or stillbirth when they meant no harm to the baby at all and are grieving the loss. I mentioned upthread a 15yo schoolgirl who was criminally investigated and her laptop and phone taken by the police, during her GCSEs, after her stillbirth. The coroner concluded that the baby died of natural causes. No pregnant woman or girl should fear that a miscarriage or stillbirth will get her arrested. In Northern Ireland, they already don't fear that.
