מַתְנִי׳ מַרְחִיצִין אֶת הַקָּטָן בֵּין לִפְנֵי הַמִּילָה וּבֵין לְאַחַר הַמִּילָה, וּמְזַלְּפִין עָלָיו בַּיָּד, אֲבָל לֹא בִּכְלִי. רַבִּי אֶלְעָזָר בֶּן עֲזַרְיָה אוֹמֵר: מַרְחִיצִין אֶת הַקָּטָן בַּיּוֹם הַשְּׁלִישִׁי שֶׁחָל לִהְיוֹת בְּשַׁבָּת, שֶׁנֶּאֱמַר: ״וַיְהִי בַיּוֹם הַשְּׁלִישִׁי בִּהְיוֹתָם כּוֹאֲבִים״.

MISHNA: One may wash the baby on Shabbat, both before the circumcision and after the circumcision. And one may sprinkle hot water on him by hand but not with a vessel, in order to depart from the usual manner in which this is done. Rabbi Elazar ben Azarya says: One may wash the baby on the third day following his circumcision, even if that third day occurs on Shabbat. On the third day following circumcision, the baby is considered to be in danger, as it is stated with regard to the men of Shekhem, who were circumcised: “And it came to pass on the third day, when they were in pain” (Genesis 34:25). This teaches us that on the third day the pain of circumcision poses a danger.

יכין ט:טז

ויהי ביום השלישי בהיותם כואבים והאידנא נשתנה הטבע. ולהכי אין מרחיצין סתם מילה. רק ביש לחוש לסכנה. אבל קודם המילה. מרחיצין אותו בחמין שהוחמו מע"ש. ובנשפכו יביא חמין שהוחמו לצורך עובד כוכבים. אבל לא יאמר לעובד כוכבים לחממן. ולענין שרית הסדין (ווינדעלן) למילה. באפשר יעשה ע"י עובד כוכבים (של"א ס"ט. ועי' בל"ט מלאכות במלבן):

Interesting point if we say nishtaneh hateva, nature changes, by physical health which is less mutable, certainly by psychological issues.  Therefore many of the parenting or psychological ideas represented in Chazal, which MAY be excellent, MAY ALSO be subject to review and consideration to see if it is actually helpful or harmful today.  It requires wisdom and gravity to not be caught up in the silly trends of permissiveness and moral laxity, yet one also should be careful NOT to presume that by being obstinate and rigid and sticking with the old methods that you will be successful if you ignore common sense
