The NUK First Choice 150ml Bottle has been developed to be one of the best baby bottles to aid you and your child when making the transition from breast to bottle. NUK First Choice+ Bottles feature the original NUK orthodontic shaped teat with a special, super soft zone which adapts perfectly to baby’s palate. The teat has an extra wide lip support which simulates breast feeding as closely as possible, and the improved NUK Anti-Colic Air System minimises infant colic caused by the harmful swallowing of air, this also helps prevent the teat from collapsing. NUK First Choice+ Bottles are compatible with all First Choice and First Choice+ Teats.
