Thinking behind the Conversion Kits:
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. So when we created The Thinkster, we did so with the mindset of giving parents the ability to convert once more. This forward thinking helps save parents and the environment from needless waste.
