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.
Thinkbaby Sippy Cup handles are made from polypropylene. The spout is made from medical grade silicone.
All of Thinkbaby products are free from BPA, BPS, PA, PS, PET, melamine, nitrosamines and biologically harmful chemicals.
