Praise be to Allah.
Undoubtedly the blessing comes where Allaah wills, and it comes if a person asked Allaah to bless him in his wealth or provision, so He makes it blessed, or He makes the person blessed, as ‘Eesa (Jesus – peace be upon him) said. Allaah says:
“[‘Eesa (Jesus) said:] And He has made me blessed wheresoever I be”
[Maryam 19:31 – interpretation of the meaning]
And the blessing will be wherever Allaah puts it, as He says concerning rain (interpretation of the meaning):
“And We send down blessed water (rain) from the sky”
i.e., you gain blessing by its falling, because it makes trees and plants grow. With regard to breastfeeding, I do not remember any aayah which mentions it in conjunction with blessing in particular.
Shaykh ‘Abd al-Kareem al-Khudayr.
The Qur’aan encourages the mother to breastfeed her child naturally. Allaah says:
“The mothers shall give suck to their children for two whole years, (that is) for those (parents) who desire to complete the term of suckling”
This is a command to mothers, as the scholars explained, to breastfeed their children. The scholars also mentioned that one part of breastfeeding is obligatory, which is the yellow substance (colostrum) that is produced at the beginning of breastfeeding and which is known medically to be of great benefit in building the immune system of the child etc. Undoubtedly in carrying out the commands of Allaah there is great blessing.
And Allaah is the Source of strength.
