In order to recognize breastfeeding as a human right, promote it and guarantee its exercise, the local Congress approved the ruling on the initiative to amend and add numeral 1, section C of Article 9 of the Political Constitution of Mexico City.

With this legal amendment, the right to breastfeeding is incorporated into the local Magna Carta as a human right, considering both the best interest of the child and the free self-determination of women with respect to their bodies, and establishes that, as a result, secondary legislation must guarantee its full exercise.
