We designed these after a lot of disappointment from products that are available everywhere for babies and mothers. The Bosom Butter is an ointment that we knew in some cases may be consumed in micro amounts by baby due to the prevalence of nursing. Ingredients in other nipple ointments are disturbing to me in there high content of lanolin and chemical preservatives. So we absolutely have baby in mind and momma in mind in offering this product. 2 oz USE: between nursing, gently apply to clean skin. Store away from direct sunlight. Shelf life approximately 1 + year.
