Chapter on Breastfeeding
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 3|Chapter 47
وَ فِي رِوَايَةِ اَلسَّكُونِيِّ قَالَ كَانَ عَلِيٌّ عَلَيْهِ اَلسَّلاَمُ يَقُولُ: "اِنْهَوْا نِسَاءَكُمْ أَنْ يُرْضِعْنَ يَمِيناً وَ شِمَالاً فَإِنَّهُنَّ يَنْسَيْنَ".
In the narration of Al-Sakooni, it is reported that Imam Ali ibn Abi Talib عليه السلام used to say, "Prevent your women from breastfeeding here and there (to various children), for they may forget."
