Who was the fifth wet nurse of the Messenger of Allah, may Allah bless him and grant him peace?

What is mentioned in the books of history and biographies is that the wet nurses of the Prophet, peace and blessings be upon him, were: Thuwaybah, the freed slave of Abu Lahab (the first to nurse him for a few days), and Halimah al-Sa'diyah (who nursed him with the milk of her son, Abdullah ibn al-Harith, and he remained with her until weaning). Ibn Sa'd and Ibn al-Qayyim mentioned that Umm Hamzah nursed him for one day while he was with Halimah. So, the total number of wet nurses is three if the narration of Umm Hamzah nursing him is authentic.
