I brought my young son, who had not started eating (ordinary food) to Messenger of Allah 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. (Using translation from Bukhārī 223)
أَنَّهَا «أَتَتْ رَسُولَ اللهِ ﷺ بِابْنٍ لَهَا صَغِيرٍ لَمْ يَأْكُلِ الطَّعَامَ فَأَجْلَسَهُ رَسُولُ اللهِ ﷺ فِي حِجْرِهِ فَبَالَ عَلَيْهِ فَدَعَا رَسُولُ اللهِ ﷺ بِمَاءٍ فَنَضَحَهُ وَلَمْ يَغْسِلْهُ»
