Featuring their signature, cross-cut design to prevent spillage, Thinkbaby's bottle nipple mimics natural breastfeeding as it requires your little one to nurse to receive fluid. The anti-colic nipple helps reduce gas and spit up, while the unique one-piece design eliminates tricky cleaning and assembly. Extra soft, medical-grade silicone provides easier transition from breastfeeding to bottle-feeding. Free of Bisphenol-A (BPA), phthalates, nitrosamines, lead, PVC, PET, and biologically harmful chemicals.

The collar, bottle and top are all made from polypropylene (No. 5. Plastic). The nipple is made from medical grade silicone.
