The horn cover is only the size of the manufacturer
Some mothers experience nipple pain, injury, and areola edema after using a breast pump. It is very likely that the size of the horn cover of the breast pump is not suitable, because most breast pump manufacturers are equipped with standard horn covers at the time of purchase. The size is 24mm, so mothers don’t know that there are other sizes to choose from. In fact, the relationship between the nipples and the horn cover is like the relationship between our feet and shoes. It must be matched in size to go far.
