Safest infant bottle

Pura bottles:

Interchangeable lids & nipples means your adult bottle can become a infant bottle in seconds

Several years ago, Sheryl Crow said drinking water from plastic bottles left in a hot car gave her breast cancer. I didn’t believe it until I learned that research has shown certain chemicals in plastic products, when the product is scratched or heated, can leech toxic chemicals into your water or food. One of the chemicals, Bisphenol A (BPA), acts as a hormone disruptor and at certain levels, BPA may cause cancer. Freaky, right?

But many companies started to remove the BPA from their products. Yay, until you realize BPA-free doesn’t necessarily mean the products are safe from toxic chemicals. They removed the BPA but those bottles still may have other harmful acronyms like BPS, EA, PVC, PAH, and phthalates. I’ll save you the explanation of each as reading about all the chemicals and what they are in has made me not want to breathe, eat, or touch anything. At all. Ever again.

Before I had my son I couldn’t have cared less about this topic, though. It wasn’t until I did what many expecting mothers do and began reading up on all the things that could go wrong while pregnant and went into a fear-inducing spiral that ended up with me settling on glass baby bottles. I would have gone with stainless steel if I had known about them six months ago, though.

I have loved my glass bottles for the most part, until recently. I can see how much milk is left in the bottles with the outer markings and I can avoid many of the harmful chemicals found in plastic bottles. But the glass got hot quickly and would burn my hands if left in the warmer too long. They had a hard time maintaining temperature, when I would try to switch bottle nipples, they wouldn’t all fit correctly, causing leakage. They are too heavy for my son to hold on his own, and well, what should have been obvious to me…they break when dropped.

And as fate would have it, the first time I had a glass bottle break was in 90 + degree weather at Disneyland with a hungry, screaming baby when I was already past my breaking point. I cut my hand trying to pick up the glass, and then realized that I only had enough formula to make one more bottle because the bottle I dropped had been full. I was tempted to just lay on the pavement and let the elements take me.


Thankfully, I had brought along the Pura Kiki Stainless Steel Infant Bottle that I had learned about a week earlier and decided to try. I was skeptical about it as anything more than just another bottle to add to the rotation but quickly learned its benefits.

After the bottle break, I bought more formula and then decided to try out the Pura Kiki Stainless Steel Infant Bottle. I had brought the 5 OZ bottle with sleeve, a pack of silicone sealing disks, and two different Pura silicone nipples—the natural vent nipples for 3 months plus and the XL Sipper Spouts for 6 months plus.

Because I had one of my other bottles already filled with formula, I decided to test out how well the bottle keeps temperature. I filled the 5oz bottle up and popped in one of the 100% plastic free sealing disks. You pop the top in from the bottom.

I then carried it around for 6 hours in direct sunlight—temperatures still above 90 degrees. It was 3pm and we headed straight for the outdoor pool with bottle in tow.

We then walked around Disneyland and by 9pm the ice had all melted. However, the water inside was still freezing and when tipped upside down, no contents leaked. The disks turn the bottle into a food container or breast milk storage container as well.


The next day I traded the silicone disks for the natural vent nipple for 3 months plus. I filled the bottle with water by looking at the internal markings.

I wasn’t thrilled to find that the highest markings were 100 ML and 3 OZ. When formula feeding, the measurements tend to be broken down in  2 ounce increments. You put in one scoop of formula for every 2 ounces of water. Typically my son eats 4 ounces or 120 milliliters of formula per feeding. This bottle can hold up to 5 ounces, but I had to guesstimate where the 4 ounce mark would be. Also, unlike the glass or plastic bottles, you only know how much the baby had drank by opening up the bottle and looking inside.

This is just the smallest type – Pura sells bigger infant bottles.

Because I was using a bottle for younger infants, I chose not to add in any rice cereal to the bottle. The 3 months plus nipple is not meant for thicker liquids.

I gave the bottle to my son to see his reaction to the new bottle. He is 6 months old and is attempting to hold bottles on his own. The bottle was light enough for him to hold. The silicone sleeve made the bottle easier to grip. When held upside down, it didn’t leak from anywhere but the nipple hole, which only released a drop or two.

My son is used to higher flow nipples, so he played with his bottle a lot.

He dropped the bottle several times from about a foot high and luckily it didn’t dent or show any obvious scratch marks. My fingerprints do show up all over it, though. Here it is after just being picked back up and feeding Little Man.

When I got home from vacation I tried the XL Sipper Spout for 6 months plus with the 5OZ bottle. My first order of business was to turn the bottle over to make sure it didn’t spill because the box says “no spill opening.”

Voila! No spill!

I was able to get my son used to the Natural Vent Nipples pretty quick, but he refused to try the XL Sipper Spout. He is very particular about bottle nipples—he has been since day one and the flat top was just too foreign to him. I do think that when he is teething he would love them. The spout is soft and durable as it advertises and I squeezed the spout and the milk comes out just fine. Babies are finicky.

Luckily, every Pura lid works with every Pura bottle and I just switched the top back to the original nipple we tried. While at Disneyland, I noticed a random guy using Pura Kiki bottles. He let me be a creep and take a picture of some of the bottles he used. See how the smaller bottle was able to use the same lid as the larger ones? If I got a larger Pura bottle I could even put the Natural Vent Nipple, Sipper Spouts, or Silicone Sealing Disks on them. Genius!

Bottles for adults & kids

Overall I would recommend the Stainless Steel Infant Bottle, Silicone Sealing Disks, Natural Vent Nipples and XL Sipper Spouts.

They are plastic-free, so no need to worry about harmful chemicals leeching into your babies bottle through the container or lids, shatterproof—great for babies who love to drop and throw things, the lids are interchangeable—every Pura top works with every Pura bottle, cold contents stay cold and hot contents stay hot for long periods of time, they are light enough for babies to hold and easy to grip with the silicone sleeve—the sleeve also keeps your hand from burning or freezing based on the inside contents, and they are dishwasher safe!

Your turn to drink!

Don’t put the bottle in the microwave, though—for obvious reasons.

It's non toxic, it's hard to break, and it's well made! This baby bottle is a winner
