When we introduced the Thinkbaby over 7 years ago 95% of the baby bottles on the market were made of polycarbonate which contains BPA. Initially, we attempted to convince the major companies to move off of polycarbonate, but after being unsuccessful we launched Thinkbaby and Thinksport to address the concern of chemicals leaching from consumer products.

Thinkbaby started with the baby bottle because polycarbonate was ubiquitous across the industry. As little ones systems are still in a state of development they have very little defense against foreign chemicals therefore, all of our bottles are free of - Bisphenol-A (BPA), phthalates, nitrosamines, lead, PVC, PET, and biologically harmful chemicals.
