If you treat your LilyPadz carefully and according to the instructions, you can reuse them for many months. They effectively prevent the leakage of valuable breast milk. They are non-absorbent and self-adhesive, made of breathable high-tech silicone. They can be used for weeks or months, making them much cheaper and more environmentally friendly than conventional disposable nursing pads. They feel like a second skin and are usually invisible under clothing. Recommended by lactation consultants, midwives, and mothers.
