Changing Diapers in the Proximity of Sefarim

Question: Is it permitted to change a baby’s diaper in the vicinity of or in a room with sefarim? If it depends, what are the parameters?

Answer: We start with sources (including a thorough teshuva by the Machazeh Eliyahu 5-6), from which we gleaned many of our sources. However, we must also think in terms of common practice and feasibility.

The halachic issues are exposing holy articles to private parts and to excrement. Regarding the former, the pasuk (Devarim 23:15) requires separation between uncovered private parts and holy things (see Shabbat 150a). The Gemara (Shabbat 120b) says that one upon whose flesh Hashem’s name is written may not bathe because it is forbidden to stand naked in front of the name of Hashem. The Magen Avraham (45:2) extends this prohibition to wearing tefillin or bringing Torah texts into a place where people are undressed. The Shemirat Shabbat Kehilchata (24:30) says—based on this—that one may not erect a partition before holy sefarim on Shabbat to allow removing a baby’s diaper because it is a halachically necessary wall.

However, there are strong grounds to distinguish between an adult and a baby. While the Shulchan Aruch (Orach Chayim 75:4) forbids reciting Kriat Shema before the private parts of a young child, the Rama (ad loc.) permits it until the age of three for a girl and nine for a boy. Even those who forbid it, do so as a chumra lechatchila (Mishna Berura 75:5) because of its impact on one’s thoughts (not as an objective “erva”), and this should not be a problem for holy articles (see Radbaz V,1028; Machazeh Eliyahu ibid.). While the Rama (Orach Chayim 275:12) cites a minhag not to leave a naked child before Shabbat candles because of disgrace to the mitzvah, it is illogical to apply the minhag to changing a diaper. (When Shabbat candles alone provided light, were parents expected to change diapers in the dark?!).

The other issue is the excrement in the diaper. (Only at the age of several months is a baby’s stool problematically unseemly—Shulchan Aruch, Orach Chayim 81:1.) One is forbidden to bring holy things such as tefillin into a bathroom (Shulchan Aruch, Orach Chayim 43:1). However, the problem is likely not the excrement itself, but the status of the place and/or the possibility he will relieve himself while there. Indeed, the Magen Avraham (43:11) permits (when necessary) going into alleyways with excrement with tefillin on. It is also more lenient when the exposure of the holy article to the unseemly matter is passing (Biur Halacha to 43:5; Shut Ramah Mipanu 59). The Machazeh Eliyahu (ibid.) proves that the exposure is not forbidden from the fact it is permitted to urinate with tefillin on if it is not in a set bathroom (Shulchan Aruch ibid.), even though sources indicate that is at least as bad as exposure to excrement.

How can we be so lenient considering the prohibition to recite holy things within the vicinity of excrement (Brachot 25a; Shulchan Aruch, Orach Chayim 79:1)? The Machazeh Eliyahu explains that it is not the proximity between the holy utterings and the unclean surroundings but when a person’s domain is impacted by an unclean area, he becomes unfit to engage in holy things. If an area becomes taken over by the excrement, then holy things cannot be done there, but a limited amount of time in which a room contains excrement does not have this impact.

What will one following stringent opinions do about mezuzot? Shemirat Shabbat Kehilchata (ibid.) presents a not-simple leniency—the wrapping of the mezuzah, which many anyway do, counts as a separation. We believe that the stringency is unnecessary in the first place, as above. Furthermore, the way our houses now have sefarim, Torah-based wall hangings, etc. all over the place makes it impractical to be machmir regarding changing diapers, and it also makes the encounter not offensive. It is not surprising that the broad practice is to not require precautions when changing diapers in regular areas. We hope our homes are blessed with several children and many sefarim and that changing diapers does not cause undue difficulty.
