question #1 Sahih al-Bukhari 223, Book 4, Hadith 89 : How did the Prophet Muhammad (ﷺ) handle situations involving children’s natural actions, such as urination?

I brought my young son, who had not started eating (ordinary food) to Allah’s Messenger (ﷺ) who took him
and made him sit in his lap. The child urinated on the garment of the Prophet, so he asked for water
and poured it over the soiled (area) and did not wash it.
