What are the guidelines for the 3 fasts before Bas Mitzvah?

 

The myth that a child should fast on the 3 fasts before his/her Bar/Bas Mitzvah has no source in Halacha.

On Yom Kippur children from the age of nine or ten are trained to fast an age-appropriate number of hours. Some have a custom to do so on Tisha B’av too, at least for the night. Children under that age must not be allowed to fast even if they so desire.

On all other fasts, children are exempt from fasting even for hours.

(Boys above Bar Mitzvah and girls above Bas Mitzvah are obligated to fast like any other adult).
