The MAM Night Pacifiers and MAM Original Matte Pacifiers bundle includes 4 total BPA and BPS-free pacifiers for babies ages 0-6 months along with a self-sterilizing case. The innovative nipple shape of both pacifier types was developed by pediatric dentists and psychologists to promote healthy oral development. The ultra-soft, skin-like silicone encourages 94% nipple acceptance and mimics the feel of a mother's breast. Both pacifier types feature symmetrical nipples that comfortably fit a baby's mouth at any angle without adjustment. The night pacifiers have glow-in-the-dark buttons to easily locate lost pacifiers in the dark. The matte pacifiers include a ventilated shield with curved openings to keep skin dry. The convenient self-sterilizing case with both pacifier sets allows for quick microwave sterilization in just 3 minutes. With multiple colors and designs, these complementary pacifier sets will meet all your baby's soothing needs while supporting healthy development.
