The Best Glass Baby Bottles of 2021 – Why Is Glass Best?

By  Paula McLaren - Norland Nurse NNEB RSH | Updated - 25 February 2021

The best baby bottles you can get are glass baby bottles. You can’t beat the longevity and sturdiness of simply grabbing a bottle of pre-made formula or milk from the fridge, heating it up and not worrying about ever damaging the bottle.

You’ll find a few glass baby bottles for less than £7 ($10), but most cost between £10 and £14 per bottle ($14-$19). While the inexpensive bottles will certainly get the job done, premium brands have convenient features such as different teats for different flow rates and nipple recreations, silicone sleeves, and extra strong thermal-shock glass.

Are Glass bottles safe?

The short answer to that is... YES. Absolutely.

Glass baby bottles are made from extra strong glass (borosilicate glass) which means they can withstand being taken from a cold fridge and heated up quickly without breaking. 

One of the other major benefits of glass bottles is that not only are they extremely durable but they can withstand all that you or your baby can throw at them. If you are extra concerned about safety you can always have the extra security of silicone sleeves for added protection.

Glass Vs. Plastic Baby Bottles

Statistically the sales of glass bottles is fast outgrowing the sale of plastic bottles and with good reason. There are many advantages to glass bottles over plastic.

  • They are easy to clean
  • They do not harbour bacteria (so they won't smell bad!)
  • They are durable and remain in good condition for years with no discolouration or scuffing
  • Glass bottles are thermal-shock resistant
  • Glass bottles are eco friendly

Glass Baby Bottles - The Eco Friendly Option

Glass bottles by nature are more eco friendly than plastic bottles. They are easily recycled and will last for years and years. 

Certain glass bottles are super eco friendly such as:

How To Care For Glass Bottles

You can care for your glass baby bottles in much the same way as you would plastic bottles. You should always wash your new baby bottles before the first use to wash off any dirt and grime from the packaging and I would also then sterilize them before using. 

Most glass baby bottles can even go in the dishwasher too - just be sure to check the product information first.

How To Sterilize Glass Baby Bottles

You can sterilize your glass bottles in one of three ways.

  • Hand washing with a mild detergent and then boiling in hot water for 5 minutes.
  • By putting all parts on the top rack of the dishwasher after having hand washed with a mild detergent first.
  • In a sterilizing unit again after having hand washed first.

Some glass bottles say that they can be sterilized in the microwave but I have never been an advocate of this method and would always choose to do one of the above.

If you’re looking for a sterilising unit, be sure to check out my Parenting Toolbox Feeding Page for my top recommendation!

How To Warm Glass Bottles

Interestingly baby’s do not need to have warmed milk but they do prefer it NOT being ice cold. After all breast milk is body temperature and this is what they like best. 

While it is always best to make up a feed fresh when you need it that is not always practical or possible. If you have a prep machine then warming is not an issue as they do it all for you rather like a fancy coffee machine.

However, as wonderfully convenient as they are... they are NOT essential. 

Most baby glass bottles are made from thermal shock resistant glass so can be warmed up directly from the fridge but check the manufacturers instruction leaflet first.

Feeds made up in advance and stored in the fridge can be heated up in the following ways:

  • In a jug of warm water
  • In a bottle warmer (check if the bottle warmer can heat glass bottles as some do not)

Testing the temperature of the milk on the inside of your wrist is still the best way to judge if the milk is warmed enough.

It is not recommended that you heat a baby feed in a microwave as it heats too unevenly and NEVER reheat a bottle once formula or breast milk has come into contact with saliva as it has the potential to grow bacteria if reheated. 

Top 5 Features to Look For When Choosing Glass Baby Bottles

1. Easy to hold

Ensuring your baby bottles are easy to hold is a MUST. You don't want to have to be constantly changing your grip when feeding baby and you certainly don't want to drop the bottle on baby either!

2. Not too heavy

Choosing a baby bottle that isn't too heavy means that your little one can hold the bottle as they grow up. Babies love to test their independence and being able to pick up a bottle and feed themselves is the first step in this journey.

3. Easy to clean

You will thank your lucky stars that you did. Choosing dishwasher safe bottles is always great, but a well shaped glass bottle will be very easy to clean by hand too.

Keep an eye out for the teats though! As they can prove a little tricker to clean. 

4. Silicone covers

As mentioned above, having a good grip is very handy for baby bottles. Not only will this help baby hold them, it will also ensure the bottle does not slip as easily. 

Silicone covers also help to ensure your baby bottle is less likely to roll off a surface too.

5. Can withstand quick temperature changes -  thermal shock resistant 

This is one of the major benefits of choosing glass over plastic baby bottles. Therefore, you will need to choose glass bottles that can withstand quick temperature changes such as going from a cold fridge to a bottle warmer. 

Plastic can degrade over time when exposed to these changes, whereas glass will not.

How many bottles do I need?

To start with I would recommend having between 5-10 bottles for your newborn depending on whether you are exclusively breastfeeding or not. If you are planning on expressing then take that into account.

You should start off with 4oz bottles and then transition to 8oz or 9oz bottles at around 4 months. 

Are Glass Bottles Worth It?

Bottom Line: Yes!

Glass bottles are definitely worth the investment as they will last not only for your first child but future children as well. They do not become scuffed and faded over time and will stay looking as good as new for years to come. 

Glass baby bottles are obviously more eco friendly and easier to clean than plastic bottles and are less likely to hold and grow bacteria. Really what is there not to like?
