Is it mentioned in the Holy Qur’an that "every drop of natural milk" is blessed, and that God blesses breastfeeding?

Blessing (barakah) descends where Allah wills, and when a servant supplicates to Him for blessing. Blessing can also be found in individuals and in rain. The Quran encourages breastfeeding by the mother for her child. This is a command to mothers to breastfeed their children for two full years. A part of breastfeeding is obligatory, which is the yellow colostrum, due to its great benefits in building the child's immunity. There is immense blessing in fulfilling Allah's command and responding to it.
