Experts analyze that due to the increase in breast weight in lactating women, daily walking or occasional vigorous running can cause breast vibration. If there is no support object to support breast weight for a long time, the breasts may cause sagging and outward expansion due to the gravity of the Earth. Moreover, during breastfeeding, the breasts will secrete milk irregularly. When milk wets clothing, it creates friction, causing severe pain in the breasts. Once the skin is broken, it can also lead to the growth of bacteria. So, from the perspective of breast sagging and health, it is necessary for mothers to purchase nursing bras, and they should also purchase several professional nursing bras for replacement.

In fact, breastfeeding bras are a type of maternal and infant product that has emerged with the needs of mothers. The main functions of breastfeeding bras are as follows:
1. Protecting breast health, preventing bacteria from invading the nipples, laying hidden dangers for women's breasts, and also preventing babies from being harmed by bacteria when sucking breast milk.
2. Support the breasts, minimize the likelihood of breast sagging or expansion, ensure breast erection, and prepare the foundation for recovery after breastfeeding.
3. Convenient breastfeeding, avoiding the embarrassment of breast exposure during breastfeeding. Many breastfeeding bras, such as the first brand of breastfeeding bras, Jingqi Breastfeeding Bra, have a breastfeeding opening on the cup of the bra, which can facilitate breastfeeding for mothers while protecting personal privacy.

According to research findings, most urban postpartum women will wear professional breastfeeding and bras during breastfeeding. This is because urban women still insist on going to work at the company during breastfeeding. Considering the needs of breastfeeding, some companies will provide breastfeeding time for women. So, many urban women choose to buy breastfeeding bras for the convenience and concealment of breastfeeding, as well as to enhance their temperament after wearing work clothes.
