Although they are not essential, you will find that breast pads and shells will help keep your nipples clean and dry.
Breast shells
When you are feeding from one breast, milk may drip or even flow from the other. A shell can be used to collect this excess milk, which can then be stored in the refrigerator for up to 24 hours or frozen.
Breast pads
Disposable and washable pads are available. They fit inside your bra and protect your clothes from leaks of milk.
