thinking behind the Conversion Kit

 When we began work on the thinkbaby system. We looked at the number of baby bottles that parents purchased and the amount of waste that was created in the movement from baby bottles to Sippy cups. What we learned was that parents purchased 8 to 16 baby bottles in the first year. Then tossed them out and replaced them with Sippy cups. This not only is a very expensive practice, but it also creates a great deal of environmental waste. So we launched a system whereby you can easily transform thinkbaby bottles into our award winning Sippy cup.

Why a baby bottle? 

 When we introduced the thinkbaby over 4 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. We 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. 

 While many companies have emerged to offer BPA Free baby bottles, many bottles not only still contain BPA despite saying BPA Free (see Health Canada study), but many companies have also landed on untested materials just because the material claims to be free of BPA. thinkbaby utilizes the precautionary principle in the creation of all of our products. We don’t jump to “new” materials without doing the requisite testing to ensure that we haven’t landed on another “BPA-like” material. When we target a product segment that concerns us, we ask the question, “How can we make the product line Safe. Functional. Sustainable.” thinkbaby and thinksport’s focus has led us to be the first company to span safe consumer products ranging from baby to adults.
