Guidance for Sleeping Arrangements for a Chuppat Niddah

May 29th, 2023|Even HaEzer, Kiddushin and Ketubah, Marriage and Family, Niddah, Yichud, Yoreh De'ah|


What do you advise regarding reasonable sleeping arrangements in the case of chuppat niddah (where halakha requires that one observe the laws of yichud)? This will be relevant for our upcoming wedding.


Mazal Tov on the upcoming wedding. Regarding sleeping arrangements—I take the position that even if the two of you are sharing an apartment, it is not yichud if you are in separate rooms with a closed door between you (some require that the woman’s door be locked. I do not require this). (See Chazon Ish Even HaEzer 34:1)

Therefore, what I advise is that until bedtime, when both of

Does a Dammed River Have the Status of a Mikveh?

May 10th, 2021|Niddah, Yoreh De'ah|


Philadelphia, PA

Can a lake that was created by damming up a river be used as a keilim mikveh? The dam is that straight line at the bottom of the lake. The lake in question is called “Henion Pond.” You can see the two rivers/streams that lead into it.



First, there is no difference between the requirements for a keilim mikveh and one for a niddah, other than a keilim mikveh does not need 40 se’ah if we are dealing with מעיין (not rain water). In such a case, a keilim mikveh needs just enough to fully cover the keli.

Bedikah For a Women With a Longer Than Average Period

May 2nd, 2021|Niddah, Yoreh De'ah|


Midwest, USA

Is there a process the Rosh yeshiva recommends for women who regularly take until day 7/8/9 to get a clean hefseik? I’m not talking about women who didn’t understand leniencies around brown and now that we look at their bedikot we can tell them otherwise. I mean women who are regularly seeing red on bedikot until those days. Would you recommend doing everything they can to get a clean hefseik (cleaning, etc.) and if they can get it, then skipping the bedikot during the first several days of 7 nekiyim (and colored underwear of course), or is this not an option?

Traveling to the Mikveh by Car on Yom Tov

March 22nd, 2021|Amirah LeGoy, Fertility, Niddah, Orach Chayim, Pesach, Yom Tov, Yoreh De'ah|


Washington, D.C.

Good evening! I was contacted by a woman who has to go to the mikveh this Motzei Shabbat, which is the first night of Pesach. She doesn’t live within walking distance of one, and is wondering if she can go on Friday, or if she has to wait until Monday night. She already practices 4+7 due to fertility purposes, so there isn’t any wiggle room there. Is there any way for her to go early? I assume not, but I wanted to check because of their ongoing fertility challenges. Thank you!


I would arrange before Shabbat to have a cab

Supportive Touch During Niddah in Case of Psychological Distress

January 1st, 2021|Niddah, Yoreh De'ah|


My wife is intensely emotional and can have difficulty regulating her feelings. The easiest way to bring her back to a more calm state is with an embrace. We have maintained no touching during niddah despite the obvious challenges associated with it.

The pandemic has been difficult for our family and we have managed, but with very high stress levels. Recently, we have become financially responsible for a grandparent, which is will be a long-term challenge. I’m wondering how I can best help to keep my wife grounded in the practical considerations and decisions we have to make when

Hefseik Taharah Before HaNeitz HaChamah

December 27th, 2020|Niddah, Yoreh De'ah|


Riverdale, NY

A woman did a hefseik taharah before הנץ החמה is it good?


Yes. It is fine.

1. Assuming it’s considered night, it’s still day 4. A hefseik taharah works on day 4, and then you can just start counting the shivah nekiyyim on day 6, as normal. Even if there is peleitat shikhvat zera on day 5, it doesn’t impact the hefseik taharah – doesn’t lead to starting over again. Actually, there is a reason

Number of Bedikot during Sheva Nekiyim

December 22nd, 2020|Niddah, Yoreh De'ah|


Do you prefer that a kallah to be taught to do 2 bedikot each day during sheva nekiyim lekhatchilah or do we hold that these days one suffices even as a standard practice? If 2 is really the preferred lekhatchilah practice, what is the standard in terms of physical discomfort, emotional anxiety, or other issues that would allow a woman to drop down to 1 per day as their standard practice?


I absolutely do not teach 2 per day. That is the position of Sefer HaTerumah 87

Guided Questions for Chavruta Learning

  1. Sources 1-7 were covered in the previous sheet.  Look at sources 8-12.  Do they indicate that a fetus has the legal status / protections of a human life or not?  Which ones indicate yes, which ones indicate no?  If one were to claim that it was a life, how would she reconcile all the sources?  How would one do so if she were to claim that it was not a life?  Is there a middle position?  How would you articulate it: quasi, potential, or something else?  What halakhic category would destroying such a

May a Husband Give His Wife Supportive Touch During Childbirth? – Part 2

April 26th, 2018|Marriage and Family, Niddah|

May a husband hold his wife’s hand or give her a massage during childbirth, according to halakhah?  We began to answer this question last week and came to the following interim conclusions:

  1. A pregnant woman is not considered to be in niddah until either she experiences uterine bleeding (distinct from mere stains), or until a limb of the baby emerges from the womb.  Prior to this time, all forms of touch are permitted.
  2. During childbirth, a woman is in the halakhic category of a person whose life is at risk, and Torah prohibitions, including Shabbat violations,
