The Closer to Nature™ bottle & teat have been designed to mimic the natural flex, feel & movement of mother’s breast, making it easier to combine breastfeeding and bottle feeding. The unique shape allows the bottle to be held closer into the body therefore allowing dads to enjoy a closeness with baby during feeding normally reserved for breastfeeding mums. The 150ml size bottle has also been designed for smaller expressed breast milk feeds. Suitable from birth. Comes with Closer to Nature™ slow flow teat.
