Reprinted, with permission, from The Taharas Hamishpacha Workbook by Rabbi David Kaufman,this checklist can be used by women having trouble estimating the amount of time they should use to prepare for Mikvah immersion. This list was approved by Rabbi Sholom Ber Chaikin, a Rav who deals especially with the laws of family purity. The timing allocations are suggestions, not Halacha, and are meant for usual circumstances. Get ready for the beautiful zechus (merit) of this mitzvah, as you prepare in a spirit of joy. This covers the Chafifah part of the preparations.
