In addition to selling gear, the Upper Breast Side refers customers to lactation consultants and doctors; hosts a weekly "latch-on clinic" for women struggling to get their babies to, well, latch on; and matches up customers with properly fitting bras. At a counter referred to as the "milk bar," bleary-eyed new mothers and their partners learn how to work a pump (the session is free if they buy one, $50 if not).
