Lifefactory glass baby bottle: Why it’s our favorite with 3 kids

When I was a brand new mom, I stumbled upon Lifefactory glass baby bottles when I was trying to avoid plastic bottles that could leak chemicals.  I knew I would be occasionally microwaving either my saved breastmilk or later on cow’s milk. I made the plunge and bought the best glass baby bottle ever and three years later still have it (and a few more ;-)! I can’t wait to show you why the Lifefactory glass baby bottle is still my favorite choice!

Why are Lifefactory glass baby bottles so great?

There are a lot of reasons to choose glass bottles, but here is why I love these ones in particular.

1. These glass bottles are durable.

Our bottles have amazed me…like the abuse they have received from my babies without breaking is a bit mind-blowing. From being thrown on the hard kitchen floor during a fit or tossed out of the stroller… Or dropped from a highchair. Or stuffed in my backpack on the bottom next to another hard object. How they don’t break, I can only attribute to the companies specialty glass which makes it so these can go from frozen temps to boiling water without breaking, and also to the amazing silicone sleeve.

Yes, we have broken a couple, but I know the silicon sleeve and specialty glass have kept us from a LOT more breaks!

These Lifefactory glass baby bottles are the best glass baby bottles! They come in 4oz or 9 oz bottles and have proven me a loyal customer. Durable, cute, and safe to drink out of. #blueandhazel #glassbottles #baby #bottles

2. Silicone Sleeve

A nice thin layer of 100% silicone protects the whole bottle. You can set this on concrete, tip it over, and know it will likely be protected from breaking. I also love the design of the holes in the silicone because silicone can sometimes get slippery if you don’t wash the sleeve all the time (I’m guilty)!

But, with the holes it does not feel slippery and it’s easy to grip. And it comes in such cute colors! O how I love the colors!! This sleeve is tricky to pull off so I rarely do, but you can soap it up and then it slips off just fine when you need to wash it really well.

3. Lifefactory bottles are BPA/BPS-free

I love knowing that when I heat up milk in the microwave, that no plastic is getting into my baby.  These bottles, sleeves, and nipples are BPA/BPS-free and phthalate-free, and dishwasher safe.

4. Bottle or sippy cup lids available

I love that for the money spent, you can use these bottles for any age baby (just get the next nipple size up). Or, they have sippy cup lids that work on both glass bottle sizes! The lid attachments available are:

  • Stage 1 nipples are 0-3 months
  • Stage 2 are 3-6 months
  • Stage 3 (6 months+)
  • Sippy Caps with a removable flow control piece inside

5. Fits other standard nipples, and most breast pumps.

As my kids have grown teeth, they have shred some plastic nipples, not going to lie! While you can buy replacement nipples for these, I have often found cheaper standard size nipples and they fit in just fine. Also the bottle screws onto most breast pumps.

Glass Lifefactory bottle used with a different nipple and lid. Nice that it is compatible!

This is a lid from another bottle we had, which did not leak, however it did not screw on as easily as the Lifefactory lids that are made to go with it. If you must use another nipple, I’d at least stick with the white lids that screw on from Lifefactory.

Downsides of Lifefactory baby bottles:

1. Glass can break

Hello, it’s glass!

But in three years, I have broken one.  I’m surprised just one! If my kids were breaking these all the time I could not afford to buy them often.  And just to let you know, when it did break, it was on asphalt as my son chucked it out of the stroller.  And asphalt is not as forgiving as even smooth concrete under a kitchen floor, so, that was that.

And, to attest to the silicone sleeve helping, I have bought several other brands that come without the sleeve, and they have broken which I think is because they don’t have the silicone.  The silicone is what makes these the best glass baby bottle!

2. Expensive.

The cheapest I have found these is around $9/bottle.  Let me tell you, its worth it.  I own three, and that’s all I need.

But, if you can upgrade the lid and use them as sippy cups, then the cost becomes even less per year or per use or whatever.

Last thoughts:

While we bought the 9 oz bottle for my son when he was guzzling the 4 oz ones (which actually hold about 5 oz when topped off)…I still prefer the smaller 4 oz bottles.  No matter what size I offer them, they drink ALL of it, haha, which means, they were peeing out of their diapers ALL the time at night and naps.

Sometimes I will give them the bigger one but only fill it to 7 oz or something.  Its nice to have the bigger option, but now you have been warned :-)!  You can get one here, you won’t regret it!

Do these come with caps, for transporting the bottles?

Hi Katherine, Ours came with a round, flat plastic piece that replaced the bottle nipple if you wanted to store or transport. Not sure if it is completely spill proof though if tipped sideways.
