Why a baby bottle? 

When we introduced the Thinkbaby bottle 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 ones 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, and 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 Sippy of Steel Cup different?

Most of the sippy cups on the market have hard plastic spouts or rubber spouts.  We built the Thinkbaby Sippy Cups with soft silicone spouts. This makes for easy transition from baby bottles to sippy cups. This is a struggle that most parents face in moving to the next stage of feeding. With the Thinkbaby Sippy of Steel, the little one is already used to the feeling of a silicone spout, so making the transition is quite simple.     

The spouts also feature a cross-cut design, so no spillage when held upside down (which obviously happens quite often). There are also no extra little pieces to lose or clean. 

The Sippy Cup has won numerous awards for both the ability to transform Thinkbaby bottles into the Sippy Cup and for the ease of transition from baby bottle to Sippy Cup.  

The Sippy of Steel is made from 304 Stainless steel 18/8. The collar is made No. 5 plastic (polypropylene) 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 baby bottle and put it up against something that can set off gas onto the product.
  
How do I care for my Thinkbaby Sippy Cup?

Thinkbaby Sippy Cups are dishwasher safe (top rack recommended). The markings are embossed into the metal so they will not come off. The logo is laser etched into the material.  

When washing the Sippy Cup 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 Cup 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. The Sippy of Steel is NOT microwave safe. In fact, we strongly suggest that parents do away with the use of microwaves for all items and products destined for your little one.
