La Leche League was founded to give information and encouragement, mainly through personal help, to all mothers who want to breastfeed their babies. While complementing the care of the physician and other health care professionals, it recognizes the unique importance of one mother helping another to perceive the needs of her child and to learn the best means of fulfilling those needs.
LLL believes that breastfeeding, with its many important physical and psychological advantages, is best for baby and mother and is the ideal way to initiate good parent-child relationships. The loving help and support of the father enables the mother to focus on mothering so that together the parents develop close relationships which strengthen the family and thus the whole fabric of society.
LLL further believes that mothering through breastfeeding deepens a mother's understanding and acceptance of the responsibilities and rewards of her special role in the family. As a woman grows in mothering she grows as a human being, and every other role she may fill in her lifetime is enriched by the insights and humanity she brings to it from her experiences as a mother.
The League's purpose is distinct. This singleness of purpose does not prevent interaction with other organizations with compatible purposes, but La Leche League will carefully guard against allying itself with another cause, however worthwhile that cause may be.
