Thinking behind the Conversion Kit

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.

Why a baby bottle? 

When we introduced the Thinkbaby over 7 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 dont jump to new materials without doing the requisite testing to ensure that we havent 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 Thinksports focus has led us to be the first company to span safe consumer products ranging from baby to adults.

How is the Thinkbaby Sippy 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 Cup, the little one is already used to the feeling of silicone so making the transition is quite simple. 

The spouts also feature a cross cut design so they do not spill when held upside down, which obviously happens quite often.  There are also next extra little pieces to lose or clean. 

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

The Sippy Cups are 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 baby bottle and put it up against something that can off gas onto the product.

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 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 chango you have our award winning Sippy Cup!!!

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.
