While glass bottles may sound new to you (with the many plastic bottles as well as silicone that are getting more popular nowadays), they are in fact, a classic that has long existed since our grandmother's era and are making a comeback in recent years, studies have found.
Today's glass bottles are quite different from the older era's as they have been upgraded to hold their own. Many parents are leaning towards using glass bottles nowadays because they are concerned that harmful additives (besides BPA) are present in plastic bottles.
1. Glass vs. Plastic
Lets talk about the pros of Glass first. It is:
- Chemical-free. Glass does not contain any chemical, so you do not have to worry about it containing any harmful additives.
- Easier to clean. Notice how there's always a film-like sheet that's left behind in plastic bottles that you can never seem to clean off? Yes, those are fats from milk (more so if it's breastmilk) and they tend to stick to the sides of bottles. It is easier to clean it off glass bottles because you can soak them in boiling hot water, which brings us to our next point.
- High thermal shock resistant. Glass can withstand high heat and therefore can be put into boiling hot water (to sterilise) or to heat up cold milk.
- Scratch-free. You will be surprised to see the many scratches your plastic bottles will come up with after multiple uses. Stop using and discard immediately if you notice this because there's no guarantee you will be able to clean the scratched area thoroughly. With glass, there is no such worry.
These benefits will have to be weighted against the cons and the first thing that comes to mind is - glass is fragile. While this is true back in the days, the glass used nowadays is tempered glass which is sturdier and is less heavy. Of course, you cannot expect it to be as light as plastic bottles, but you will certainly be surprised to see the durability these glass bottles hold nowadays.
Another thing that people are concerned of is that glass bottles are hard for babies to gripe. This can be solved easily by buying these silicone outer sleeves to give babies better friction, and also to protect your glass from shattering.
On the other hand, plastic bottles have the following benefits:
- Non-breakable. You do not have to worry about shattering your bottles. Period.
- Light. Even at their heaviest, they will still be lighter than glass bottles which is definitely a pro especially if your baby will be holding it himself.
- Cheaper. Plastic bottles are cheaper than glass. We understand this is one of its biggest appeal to many parents.
The biggest "con", or concern as we'd like to put it, is that plastic contains a type of chemical called BPA that experts have found to produce harmful effects on the brain and behaviour development of children. Most manufacturers have therefore eliminated this element from their bottle making but still, some parents have the nagging feeling - what if there are other harmful chemicals that experts haven't detected yet?
Another down side is that you cannot immerse plastic bottles into hot water (don't even think about boiling water!) because it will either melt the plastics or render the release of some chemicals from the plastic into your milk.
2. So, Which One is Better?
We lean towards glass bottles to be honest, mainly because of peace of mind that absolutely NOTHING chemical is going into baby's tummy. We also love how they can be cleaned thoroughly and be soaked in boiling hot water. Even though they are slightly pricier than plastic bottles, it works out long term wise because we don't need to dispose them as often (compare to scratchy plastic ones), well, that is if we are careful enough not to break them.
As you can see, both Glass and Plastic bottles have their own pros and cons. When it comes to choosing one, it really is a trade-off between what you want and at the end of the day, is a personal preference.

4. How to Clean Glass Baby Bottles
Just like how you will clean your plastic bottles, you do the same thing with your glass baby bottles.
Getting a brush cleaner kit like this will definitely help (to get into every nook and cranny!), otherwise, just a simple bottle brush will do the trick (this is a favourite, while this is perfect for travelling and it doesn't get any cheaper than this).
After cleaning, you should always sterilise the bottles to make sure they are 100% germ-free. This is when the perks of glass bottles become apparent - you can boil them in hot water if you do not want to spend extra money buying a bottle steriliser. This is something plastic bottles cannot achieve (if you are boiling them, you should stop now!) because the high heat will melt them, or worse, plastic chemicals that are harmful to your baby will be released.
If you do not want to be boiling water every time you need to sterilise your bottles, we highly recommend getting a bottle steriliser to make your life easier. They are very affordable and come in different varieties to suit different needs (microwave, electric steam etc.). Click here to read our extensive review on the best baby bottle sterilisers.
