If any layman or lay woman has smothered their child, let them do penance for a whole year on bread and water, and for two others let them refrain from wine and meats, and so first let them be restored to communion at the discretion of the priest, and then let such a husband use his bed lawfully. For the laity must know, that in the period of penance assigned to them by the priests it is not lawful for them to know their wives, except after the conclusion of the penance; for penance ought not to be halved.
