For new moms, breastfeeding can be a challenge, so we created the Crane lactation massager. This breast massager helps to loosen and comfort the areas around the breast, to give you the best breast feeding experience possible. The gentle vibrations from the massage help alleviate pain and soothe discomfort that is associated with breastfeeding, clogged ducts, engorgement, and mastitis.
