Prince Lionheart Hypoallergenic Pure Silicone Baby Bottle is free from BPA, Phthalate, PVC, Latex & Lead - Just pure silicone which has no open pores to harbour bacteria.
How it works:
Slowly squeeze excess air out of bottle by pinching nipple while squeezing bottle until liquid level reaches top of nipple. The Bottle will collapse as air is released. Most bottles with venting holes allow air into bottles as babies drink. Prince Lionheart’s Silicone bottle collapses as air is released giving baby a bubble-free feeding, reducing the likelihood of colic, reflux and spit-up.
