The Mishnah on Observing the Fast

8:1. [On] Yom Kippur, it is forbidden to eat, to drink, to wash, to anoint oneself, to put on sandals, or to have intercourse. A king or bride may wash their face, and a woman after childbirth may put on sandals—the words of R. Eliezer. But the sages forbid it. [ . . . ]

4. [With regard to] children: they do not “afflict” them [i.e., impose fasting and other restrictions] at all on Yom Kippur. But they train them a year or two before in order that they become accustomed to the commandments.

5. If a pregnant woman smelled [food on Yom Kippur], they feed her until she feels restored. A sick person is fed at the word of experts. And if no experts are there, they feed him upon his own request until he says, “Enough.”
