There has been a lot of discussion about the New York 2019 Reproductive Health Act signed by Governor Cuomo.

Under what conditions can a legal abortion be performed under the NY 2019 Reproductive Health Act?

Certain popular pundits claim that legal abortions may be performed post-birth if the mother claims that the child is a threat to her mental and/or physical health. Is an abortion legal in this case?

There is no time limit on performing a legal abortion. §2599-bb of the bill says that a physician

may perform an abortion when, according to the practitioner's
reasonable and good faith professional judgment based on the facts
of the patient's case: the patient is within twenty-four weeks from
the commencement of pregnancy, or there is an absence of fetal
viability, or the abortion is necessary to protect the patient's
life or health

It is left to ordinary language interpretation to understand what "abortion" is. The ordinary meaning of abortion does not include act that follow birth or a child. The law as amended still defines homicide as

conduct which causes the death of a person under circumstances
constituting murder, manslaughter in the second degree, or

criminally negligent homicide

and deleted the clause which included the clause

an unborn child with which a female has been pregnant for more than
twenty-four weeks

(this is how abortion past 24 weeks was formerly illegal). The definitions say that

A person, when referring to the victim of a homicide, means a
human being who has been born and is alive

Once a fetus becomes a person by being born, the homicide statute prohibits killing the person. So apart from the fact that killing a person is not "an abortion", the law does not make it legal to kill any man being who has been born and who is alive.
