The best stainless steel baby bottle for your baby.

The Best Stainless Steel Baby Bottles of 2018


If your looking for the best stainless steel baby bottles for your baby, we’ve got you covered.

Maybe you want safer alternatives plastic bottles or an eco-friendly way to reduce the carbon footprint of having a baby. Either way, steel bottles are a great replacement for plastic baby bottles.

Here we’ll go over the why stainless steel is safer, the features of the leading bottles, what they lack, and which one will be the best fit for you.


Why Get Stainless Steel Baby Bottles?

So why would some moms choose a metal bottle over plastic or even glass bottles?

Over the last few years, we have become more aware of the dangers that plastic can pose. One thing that surfaced about plastic is the health risks of BPA (although things like PVC and Phthalates are issues too!) Many plastic bottles are now made to be BPA free. But since the toxic nature of BPA is still a somewhat recent discovery, it brings up the question of what else could be in plastic that could harm my baby?

Plus the environmental effects of plastic make is a not so great choice.

So glass and stainless steel are preferred materials.

Stainless steel baby bottles are fantastic because they are usually well insulated and will keep baby’s milk warmer, longer. It’s easy to clean, very durable, and most are 100 recyclable!

Since glass is breakable, many moms choose steel bottles just for the peace of mind.


Benefits of Stainless Steel Baby Bottles:

  • Easily avoid harmful toxins in plastic
  • More resistant to mold and bacteria
  • Requires less energy and resources to make metal bottles vs. plastic
  • Some of these bottles will last a lifetime, especially the convertable ones!

Pura Kiki: The best stainless steel baby bottles.

The Pura Kiki Stainless Steel Baby Bottle

Our Rating: ★★★★☆
Price: $$$

The Pura kiki baby bottle is 100% plastic free, and the non-metal parts are made with medical grade silicone.

It’s also our favorite stainless steel baby bottle. It has the most features, but it’s also the priciest.

The cool thing about this bottle is that it grows into a sippy cup, and then even a stylish cup for adults. You just have to change the top out. It also fits in most cup holders, unlike some of the other metal baby bottles on this list.

Here are our favorite things about this bottle:

  • Keeps beverages warm or cold (with ice) for up to 24 hours.
  • Vented, wide-neck nipple is designed to reduce colic in babies & support breastfeeding.
  • Fits in most cupholders, both car and strollers.
  • Internal volume markings to see how much milk is in the bottle.
  • Silicone travel cover for easier grip (Comes in pretty colors too.)
  • Comes in both 5oz and 9oz sizes.
  • Warms quickly in bottle warmers.

One downside to this bottle that seems to bother a lot of moms is that it is on the heavy side and some babies have trouble holding it themselves. My concern would be with getting knocked in the head with this thing, but my babies have all been throwers.


Stainless steel baby bottle, thinkbaby brand review.

The thinkbaby Stainless Steel Baby Bottle

Our Rating: ★★★★☆
Price: $$

The thinkbaby bottle is another great metal baby bottle. It’s free from BPA, phthalates, nitrosamines, lead, PVC, PET, and biologically harmful chemicals. 

They also have a model of the bottle that comes with a handle, however many moms complain that when added to the bottle, the handle causes it to leak. Which is a shame, because other than that, this bottle is spot on.

Our favorite things about this steel bottle:

  • A one-piece design to make cleaning easy, no extra parts.
  • Anti-colic nipple to reduce of gas and spit ups.
  • Can convert into a sippy cup or thinkster straw cup

I love thinkbaby products, but one thing I am going to point out about this bottle is the plastic lid. Unlike the Pura Kiki, it’s not 100% plastic free. If that’s an issue for you, this is not the bottle for you.


The klean kanteen stainless steel baby bottle.

Klean Kanteen Baby Bottle

Our Rating: ★★★☆☆
Price: $$

The Klean Kanteen Kid Kanteen is a little less expensive than some of the others on the list, but much like the think baby, it’s not 100% plastic free. The bottle is made of stainless steel and the nipple is medical grade silicone, but the nipple attachment part is made of plastic.

This is the 5oz size, and it comes with a slow flow nipple, making it ideal for babies under 6 months.

The shape makes this bottle easier to hold for most babies than the other bottles on this list, and heats quickly in a bottle warmer or even just a cup of hot water.

This bottle is a bit wide, and some moms have complained that it doesn’t fit easily in diaper bag pockets like thinner bottles. It also doesn’t convert into a sippy cup like the Pura kiki or thinkbaby, so it’s lifetime use is limited.


cute stainless sleep baby bottle with steel lid.

Pacific Baby Hot-Tot Insulated Metal Baby Bottle

Our Rating: ★★★★☆
Price: $$

The Pacific baby bottle is definitely the most adorable metal bottle on this list. It holds 7oz of fluid and will keep milk warm up to 10 hours.

That’s perfect for an overnight feed so you don’t have to get up and warm the milk in the middle of the night, or when you’re on the go.

This bottle features cute designs, this one with little whales, and an anti-colic nipple, for less gassiness and spitting up. It also doesn’t convert into a sippy cup.
