Infanticide
(1)
Where a woman causes the death of any child of hers under the age of 10 years in a manner that amounts to culpable homicide, and where at the time of the offence the balance of her mind was disturbed, by reason of her not having fully recovered from the effect of giving birth to that or any other child, or by reason of the effect of lactation, or by reason of any disorder consequent upon childbirth or lactation, to such an extent that she should not be held fully responsible, she is guilty of infanticide, and not of murder or manslaughter, and is liable to imprisonment for a term not exceeding 3 years.
(2)
Where upon the trial of a woman for the murder or manslaughter of any child of hers under the age of 10 years there is evidence that would support a verdict of infanticide, the jury may return such a verdict instead of a verdict of murder or manslaughter, and the defendant shall be liable accordingly. Subsection (2) of
section 339 shall be read subject to the provisions of this subsection, but nothing in this subsection shall affect the power of the jury under that section to return a verdict of manslaughter.
