I think that's a very personal sort of judgement and one that should be reserved strictly for the mother. This part of motherhood is not delegable. It's a big responsibility. How it's handled will impact the resulting person for the rest of their life. The resources available to the mother (and no one else) will have a great impact.
If the mother doesn't cooperate and take her responsibility seriously, there is nothing that an busybody can do to change the situation. So the mother has to agree of her own free will or it doesn't really work.
This is why the government should not get in the middle of the decision.
It's also good public policy to support the mother in any way we can once she decides to treat "the blob" as a person. It benefits us all if she gets the best result possible.
Vitamins. Food. Medical care. Schools. Perhaps even training.
Moral Majority busybodies usually want to take all of those things away.
