927. Pregnant and Nursing Women

133:11 A husband and wife should not touch one another, not even during the day. Rather, they should distance themselves the entire day of Yom Kippur the way they do when she is a niddah.

133:12 On Yom Kippur, pregnant and nursing women must complete the fast just like everyone else. If a baby is dangerously ill and will only nurse from the mother so that fasting would pose a danger to the infant, then the mother may not fast.
