Complementing the premium glass bottles are MAM's extra slow flow silicone nipples, specially designed for newborn babies. Their skinsoft material and symmetrical shape provide a comfortable fit and feel similar to mom's skin. The nipples' unique flat design and small mouthpiece fit perfectly into a newborn's mouth.
