A pack of 4 First Choice+ Baby Bottle with Size 1 Silicone Teats. The 300ml-capacity bottles are BPA-free and are suitable for combined feeding. The bottles feature the original NUK orthodontic, asymmetrical shaped teat. Designed with a special, super soft zone which adapts perfectly to baby's palate, simulating breastfeeding as closely as possible. It is so true to nature that most babies hardly notice the difference. The teat has an extra wide lip support 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. The teat that comes fitted with the bottle features a medium size feed hole teat which is suitable for breast milk and formula. Approved by the British Dental Health Foundation. For safety and hygiene purposes replace teat after 1-2 months use or sooner should signs of wear appear.
