After each feeding, gently lay the shell on your nipple in the hollow part of it.
You can wear it after applying your skincare cream.
The shell will be held by your bra.
Wash the seashells daily with soap and rinse with clear water.
In case of infection consult a health care professional.

The lesions of cracks have the appearance of small red lines on the surface of the nipple or of fissures, or else the whole nipple may have a red and abraded appearance.
The cracks can be without visible lesions at the beginning, but the nipple is painful during feedings.
The cracks are most often due to a bad position of nursing and a bad intake in the mouth.
