...following the precepts of God and the holy Law, suckle your children from their infancy with the milk of a universal education, and rear them so that from their earliest days, within their inmost heart, their very nature, a way of life will be firmly established that will conform to the divine Teachings in all things.

For mothers are the first educators, the first mentors; and truly it is the mothers who determine the happiness, the future greatness, the courteous ways and learning and judgement, the understanding and the faith of their little ones. 
- ‘Abdu’l-Baha  (‘Selections from the Writings of 'Abdu'l-Bahá’)
