Yahya related to me from Malik from Nafi that Salim ibn Abdullah ibn Umar informed him that A'isha umm al-muminin sent him away while he was being nursed to her sister Umm Kulthum bint Abi Bakr as-Siddiq and said, "Suckle him ten times so that he can come in to see me."

Salim said, "Umm Kulthum nursed me three times and then fell ill, so that she only nursed me three times. I could not go in to see A'isha because Umm Kulthum did not finish for me the ten times."
Muwatta Malik Book 30, Hadith 7

She did it, so he used to come in to see her.
