Thinkbaby of Steel

The bottle is made from 304 medical grade stainless steel, the collar from polypropylene (no. 5 plastic), and the nipple from medical grade silicone.

How do I care for my Thinkbaby bottle?

Thinkbaby bottles 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 baby bottles 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 bottles in boiling water for 2 to 5 minutes before first use.  We do not recommend utilizing sterilizers, as we cannot guarantee that the ones on the market were made with safe materials. The Thinkbaby of Steel is NOT microwave safe. We strongly suggest that parents do away with the use of microwaves for all items and products destined for your little one.

To prepare the nipple for first use, please squeeze the top of the nipple and the venting tube. You will want to make sure that both open properly. When tightening down the collar of the bottle, do not over tighten, as this will reduce the amount of airflow into the baby bottle.

What nipple flow should I use?

Thinkbaby baby bottles come outfitted with Stage A nipples. The nipples are designed for newborns to 6 months. The flow rates are determined by averages. Depending on your little one, you may need to adjust the flow rate that you purchase. The chart below should provide help in determining which to purchase. 

Childs Age                              Suggested Flow Rate

0 to 6 months                           Stage A Nipples

6 to 12 months                         Stage B Nipples

9 to 36 months                         Sippy Cup Spouts 

18 to 48 months                       Thinkster straw top

Baby bottle nipples and spouts made from silicone will typically last 2 to 3 months prior to needing replacement.  If you notice tears or breakage, discontinue use and replace.

How does the venting system work?

The venting systems work by allowing air to travel back into the baby bottle. Movement of air back into the baby bottle allows the bottle's internal pressure to reach equilibrium. This reduces the amount of suction required to get fluid out of the baby bottle. Research shows that having a venting system reduces the incidence of gas and spit up, as children take in less air when drinking when venting systems are present. While most modern baby bottles have some sort of venting system, the advantage to Thinkbaby's system is that it is built right into the baby bottle nipple. So, there are no extra parts to deal with and it's easy to clean.

How do I convert the Thinkbaby bottle into the Sippy Cup or Straw Bottle?

How do I prevent nipple collapse?

Step 1

With cross-cut nipples, it is important that you have the right nipple flow for your child's age. The suggested age range is listed above. This is the number one reason for nipple collapse across baby bottle lines. Please note that these numbers are based on averages. If you have an especially fast or slow feeder on your hands, you may need to adjust your movement between flow levels.

Step 2

Do not over tighten the collar, as this will restrict the airflow.  

Why a baby 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 from 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 of Steel bottle different?

Simply creating a baby bottle that was safe just wasn't enough.  We went the extra mile to create a bottle that solved many parental complaints. For example, most bottles on the market contain venting systems. Our system is built right into the nipple.  So there are no extra pieces to clean or potentially lose.

We then made the nipple No Spill through our cross-cut design. This eliminated a large amount of mess that occurs during feeding. It also mimics the way children feed during breastfeeding, as it requires them to apply pressure and nurse to receive fluid. 

We also used a little forward thinking and designed the bottles to be convertible into our award-winning Sippy Cup. Most parents have between 8 to 16 baby bottles. When it comes time to move to a sippy cup, they have to go out and spend a lot of money to acquire them (while also having to toss out all of the old baby bottles which are then destined for landfills). With the conversion kit, parents can simply convert their existing baby bottles into our Sippy Cup, which not only saves them money, but it also saves the environment from excess waste.  

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.
