Fasting by pregnant and nursing women

Hi,

Regarding the fast of the Tenth of Tevet, which is observed this year on Tuesday, January 6th:

Pregnant and nursing women who are greatly pained by the fast should break their fast. These women are not obligated in the first place, although the practice is for them to attempt to fast to whatever extent they can.

(Code of Jewish Law Orach Chaim 550:2)

Have an easy and meaningful fast,
Mordechai
