Thinkbaby Sippy Cups | No-Spill & BPA Free | Ages 9-48 Months

The straws are made from medical grade silicone.
Do you conduct animal testing?
We do not conduct animal testing on any of our products. All of our testing is either chemical testing or biological testing (on cells). We utilize third-party globally certified laboratories to conduct our testing.

Thinkbaby Thinksters are dishwasher safe (Top Rack recommended). We also recommend making sure that the dishwasher is not set to a super hot setting or dry setting, as this will reduce the longevity of the straw. When washing in the dishwasher, we recommend using a detergent that is free of chlorine. Most of the natural detergents on the market from Eco Lever to Seventh Generation 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.
Before first use, we recommend sterilizing the straws in boiling water for 2 to 5 minutes before first use. We do not recommend utilizing sterilizers, as we cannot guaranty that the ones on the market were made with safe materials.

Why a straw bottle?
When we introduced the Thinkbaby over 8 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 one's 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.
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 happensÑquite often. The top of the bottle features an 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.

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.

How do I care for my Thinkbaby Sippy Cup?
Thinkbaby Sippy cups 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 the 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 the Sippy cups in the dishwasher, we recommend using a detergent that is free of chlorine. Most of the natural detergents on the market from Eco Lever to Seventh Generation 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.
Before first use, we recommend sterilizing the Sippy cups in boiling water for 2 to 5 minutes before first use. We do not recommend utilizing sterilizers, as we cannot guaranty that the ones on the market were made with safe materials. 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.
How do I convert the Thinkbaby bottle into the Sippy Cup?
One of the great things about the Thinkbaby system is that you can convert the baby bottles into our award winning Sippy Cups. Simply purchase the Thinkbaby Conversion kit from your local retailer or online. To convert, remove the baby bottle nipple and replace with the Sippy Cup spout. Then place the Sippy Cup handles around the top of the baby bottle and push down over the neck of the bottle. Tighten the collar with spout around the neck of the bottle and.presto-changeo you have our award winning Sippy Cup!
