# If it will cause a fight among the family to perform the Brit Milah very early, one may delay it, but one should still try to make it as early as possible.<ref>Rav Mordechai Eliyahu's comment on Kitzur S"A 163:1</ref>
# If there is a concern of a health risk to the baby, the Brit Milah should be delayed until the baby is healthy. Once the baby is healthy, in the case of some illnesses the Brit Milah should be performed without delay, while in other cases, the Brit Milah is only performed after 8 days after the baby became healthy. <ref>S"A 262:2, Kitzur S"A 163:4</ref> Needless to say, because of the complexity of these issues, it is incumbent for a person to consult an Orthodox Rabbi to assess the situation. For more details about a delayed Milah, see the [[#A Delayed Milah]] section.
# If a baby is born during [[
Ben HaShemashot]], since there is a doubt whether it was day or night, the Brit Milah is performed on the ninth day from the baby's birth. <ref>S"A YD 162:4</ref>Because of the complexity involved in practically determining [[ Ben HaShemashot]] an Orthodox Rabbi should be consulted.<ref>Kitzur S"A 163:6</ref>
==Brachot for the Brit Milah==
# The Mohel makes the Bracha "ברוך אתה ה' אלוקינו מלך העולם אשר קידשנו במצותיו וציונו על המילה" (“Baruch Atta Hashem Elokenu Melech HaOlam Asher Kiddeshanu BeMitzvotav VeTzivanu Al HaMilah”) prior to the Milah. <ref> S"A YD 265:1 </ref> This bracha should be said standing. <ref>Rama YD 265:1 </ref>
* Sh”t Yabia Omer YD 5:23, Menuchat Ahava (vol 1, 1:6), and Rav Mordechai Eliyahu (comments to Kitzur S"A 163:4) accept the Chida as halacha.
* However, the Sh”t Tzitz Eliezer 12:43 rejects the Chida because he points out that the Tashbetz himself wasn’t sure whether to hold like Rebbe that one must stipulate or Rabben Shimon and one wouldn’t have to stipulate and only as a stringency did the Tashbetz hold like Rebbe. The Tzitz Eliezer concludes that it’s illogical that the Tashbetz would have postponed the Milah from Thursday just because of a stringency of holding like Rebbe. [See further in the Birkei Yosef who gives a second defense of the Rashbetz and Tzitz Eliezer who rejects it as well.] </ref>
# Everyone agrees that if a baby boy is born during the [[
Ben HaShemashot]] (halachic twilight) on Wednesday can have the Brit Milah on Thursday next week. <Ref>Menuchat Ahava (vol 1, 1:7) and Sh”t Yabia Omer YD 5:23(4) explain that since the Brit Milah’s original time was set for Thursday because of a doubt it’s not considered like it was delayed specifically for that time. </ref>
