Designed to feed baby naturally, these Philips AVENT bottles have large teats which mimic the shape of the breast, helping baby to learn to alternate between breastfeeding & bottles. Ergonomically shaped for extra comfort. Soft, flexible teats & refined anti-colic valves ensure air enters the bottle & not babys tummy. Comes with 2 soft flow teats (suitable from 1 month). Additional teats sold separately on this site. In polypropylene, guaranteed BPA-free. Always check temperature before giving baby the bottle. Please note: this is a green star item; no extra discounts will apply.
