  5. Minchat Yitzchak (Dayan Weiss) is strict on diapers. Sh”t Bear Moshe 6:14 is lenient about using pampers on Shabbat since it’s only a temporary connection. Sh”t Tzitz Eliezer 16:6 is lenient because it isn’t not even considered temporary. 39 Melachot (Rabbi Ribiat; pg 813) permits since the tabs are made to be used that way. Children in Halacha (Rabbi Simcha Bunim Cohen; pg 212-3) is lenient. See http://www.dailyhalacha.com/Display.asp?ClipDate=7/25/2005.

  7. 39 Melachot (Rav Ribiat; pg 814), Rabbi Mansour (http://www.dailyhalacha.com/Display.asp?ClipDate=7/25/2005) holds similarly.
  8. Sh”t Igrot Moshe 2:84 permits
  9. Korban Netanel (Shabbat perek klal gadol 7:50) forbids using a safety pin on Shabbat by putting the safety pin through a cloth. However, the achronim including Sh”t Igrot Moshe 2:84, Shemirat Shabbat KeHilchata 15:70, and Kitzur Hilchot Shabbat (pg 67) permit because the pin doesn’t connect the two objects but rather keeps them close together like buttons.
  10. 39 Melachot (Rabbi Ribiat pg 818), Shemirat Shabbat KeHilchata 15:74 permit. Sh”t Shevet HaLevi 3:51 is strict unless it’s temporary (within 24 hours?). Rav Shechter (quoted by Rabbi Rosner) is strict for this opinion and doesn’t zipper his Shabbat talit bag because of this.
