NUK First Choice+ teats have an orthodontic shape and super soft zone which simulates the shape of a mother's nipple during breastfeeding. This makes it easier for baby to accept and for mum to alternate between breast and bottle-feeding. The natural shape of the NUK teat also perfectly adapts to baby's sensitive palate and helps exercise their jaw and teeth, while the NUK Anti-Colic Air System minimises infant colic caused by the harmful swallowing of air. The Flow Control Y-cut on the teat also allows baby to regulate their drinking intuitively and is suitable for all types of liquid. They help the transition to independent drinking and are suitable for combination feeding, as the extra wide lip support simulates breastfeeding as closely as possible. The innovative Anti-Colic vent helps prevent the harmful swallowing of air. These teats fit all NUK First Choice+ bottles, are BPA-free and made in Germany.
