thinkbaby Sippy Cup or Bottle Conversion Kit
How is the thinkbaby straw bottle different. Most of the sippy cups and straw bottles on the market have hard plastic spouts or rubber spouts. We built the thinkbaby straw bottle with soft silicone straw. This makes it perfect for the advancement to the next stage in feeding.  The straw features a cross cut design so they do not spill when held upside down, which obviously happens…quite often. The top of the bottle features a easy to close cover to keep it from coming into contact with foreign substances.. The Sippy cup and thinkster have won numerous awards. There are also quite a few YouTube postings from parents delighted with them. The thinkster is made from No. 5 plastic and therefore can be recycled after use. You may also notice that we do not use clear plastic windows with our products. We have found that these windows are made from PET or PVC. It doesn't make sense to take a safe bottle and put it up against something that can off gas onto the product.
