Thinkbaby THINKSTER Straw Bottle - 9 oz

How is THINKBABY's THINKSTER straw bottle different? Most of the sippy cups and straw bottles on the market have hard plastic spouts or rubber spouts. We built the THINKSTER with soft silicone staw. This makes it perfect for the advancement to the next stage in feeding. The straw features a cross cut design so the bottles don't 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 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.

We recommend sterilizing the THINKSTER in boiling water for 2 to 5 minutes before first use. We do not recommend utilizing sterilizers. If you are currently a THINKBABY user, you can simply upgrade to the THINKSTER by purchasing the THINKSTER CONVERSION KIT. While the baby bottles are technically microwave safe, we strongly suggest that parents do away with the use of microwaves for all items and products destined for your little one. With all baby feeding products, they should be taken away after feeding is over and children should never be left unattended during feeding. For all baby bottles, sippy cups and straw bottles, it is necessary to replace parts when they show signs of wear.

How do I care for my THINKSTER? THINKSTERS are dishwasher safe (Top Rack recommended). Please take care not to wipe the measurement markings. We do not use lead in our paint, which is what predominately makes paint stick. The US and EU standards actually allow for low levels of lead. We specifically do not want lead in our products. When washing THINKSTER in the dishwasher, we recommend using a detergent that is free of chlorine. Most of the detergents available at natural markets should be free of toxic chemicals. If hand-washing, the American Pediatrics Association suggests using warm soapy water, but only if you live in an area with treated water systems.
