The small bumps next to the nipples should be Montgomery’s nodules, which are formed by the bulging of the openings of the Montgomery’s glands. Montessori nodules are large sebaceous glands that secrete milk and are mainly used to secrete oil to protect the nipple and areola, as well as to lubricate the nipple and the baby’s mouth and lips. These nodules are affected by the increase of estrogen and progesterone and will gradually become more prominent after one to two months of pregnancy. They are accompanied by darkening of the areola, development of breast follicles and lobules, and enlargement and engorgement of the breasts. If there is no other discomfort, don’t worry too much. Pay attention to breast hygiene, especially at the nipples, don’t wear tight underwear, and keep your mood comfortable. If there is redness, swelling and infection, you should pay attention to local hygiene, disinfection with iodophor and topical application of mupirocin ointment for symptomatic treatment.
