为什么要使用护盾？
breast shields are used to help mothers to aid in breastfeeding, when they are having problems like the baby is having trouble latching, one or both of the mother’s nipples are flat or inverted, or they have a cracked nipple, etc.   
它也可用于早产婴儿以有效地母乳喂养他们。
breast shields gives a definitive shape to mom’s nipple, making it easier for the baby to latch onto and start sucking. for mothers who have cracked or pained nipples, a breast shield serves as a temporary barrier so that the baby can still breastfeed while allowing mom’s nipples some time to heal.
