Are glass baby bottles better than plastic bottles?

Glass baby bottles quickly fell out of favor when lighter, cheaper plastic baby bottles came along. But glass baby bottles are now making a comeback, not just because they look cool, but as an environmentally conscious and practical alternative to plastic bottles. So, what’s the deal on glass vs plastic for your baby’s bottles?

Glass baby bottle advantages

No need to panic when you hear ‘glass’ and ‘baby’ in the same sentence, modern glass baby bottles are a lot safer than they were back in the day. Most glass baby bottles are made from specially tempered glass, which is very hard to break and forms small glass pebbles, rather than sharp shards if it does smash.

  • Glass bottles are naturally chemical and toxin free

Glass is made without using harmful chemicals (like BPA) that could leach into your baby’s milk. (Don’t worry all Tommee Tippee bottles – glass or plastic, are BPA Free).

  • Won’t pick up smells and stains

No need to worry about pesky odors sticking around. Your glass bottles don’t stain or pick up odors from its environment (we’re looking at you Bolognese pan in the dishwasher), so you can be sure that your baby is getting the great taste of breast milk and nothing else!

  • Long lasting and recyclable

Glass baby bottles are popular with eco-conscious parents because glass is made from naturally abundant materials and it can be reused and recycled many times. One set of glass baby bottles can last for years through more than one child’s feeding journey, you’ll just need to change nipples regularly.

When you’re done with your glass baby bottles, they are 100% recyclable, with glass recycling much more easily accessible than plastic recycling – but make sure you check with your local recycling provider!

  • Durable and easy to clean

Glass baby bottles pick up fewer scratches than plastic bottles so it’s easier to see when they are dirty. Glass can also withstand high temperatures, so you can wash glass baby bottles in hot water and sterilize them by boiling or other high heat sterilization methods like steam sterilizers.

  • Never distort or bend

Baby bottles are designed with little fingers in mind, so holding their original shape is a must! Glass baby bottles won’t become misshapen when heated.

  • Multi-purpose use

Some glass bottles can be used for more than baby milk. The Tommee Tippee 3-in-1 glass bottle can be used for milk with a nipple, a cup with handle and a food storage jar with a lid.

This is Mom approved with proof from our trusted partner, Hilaria Baldwin:

“I'm super excited about the 3-in-1 bottles because they're stage appropriate for all my children. As they go from bottle to cup to container they've been fun to bring out on our picnics because they're shatterproof and super kid friendly #nipplevision


Glass baby bottle disadvantages

  • Glass bottles are heavier than plastic

Glass bottles can add to the weight of all that baby stuff you carry around with you. Plus the weight of a glass bottle means your little one may need to be a little older and stronger before they can hold for themselves.

  • Glass is more expensive

Sure, individually a glass bottle is likely to cost more than a plastic one, but if you think about the cost per use, and how long they last, it may be worth making the extra investment.

Plastic baby bottle advantages

  • Plastic bottles are lightweight

With so much stuff you need to look after your baby, anything that helps lighten the load is welcome, especially if you’re travelling, so plastic bottles are often the convenient option. Plus, they’re easy for baby to hold.

  • Plastic baby bottles are widely available

You can find plastic baby bottles at many chain stores, supermarkets and local retailers.

  • Less expensive than glass

Plastic baby bottles tend to be cheaper than glass bottles because they are easier and less expensive to produce. But watch out for quality and buy from brands you can trust (Tommee Tippee 😉).

  • Won’t break
    Plastic bottles might not last as long as glass, but they’ll be fine if dropped (or thrown) by tiny hands!

Plastic baby bottle disadvantages

  • Some plastic bottles (not ours) contain BPA
    In the past, plastic bottles often contained a chemical compound called BPA which could have potentially harmful effects on babies. Tommee Tippee plastic bottles are 100% BPA free, but it’s still worth noting if you’re considering a switch to glass.
  • Plastic bottles could be tougher to clean than glass

Plastic baby bottles can’t withstand super high temperatures for cleaning and sterilizing, and they may become misshapen and damaged over time. Glass bottles are made to last and won’t morph in the dishwasher.

  • Plastic isn’t always fantastic

Over recent years we’ve all become more aware of the problem of plastic waste. Once it’s outlived its use, it can take 450 years or more for a typical plastic water bottle to decompose, and even if it can be recycled, plastic often ends up in landfill.

What to look for when buying glass baby bottles

If you want to use glass bottles to feed your baby, then look for quality and choose a brand you can trust.

  • Consider the weight of the bottle and what kind of glass it’s made from. Tommee Tippee’s glass is recyclable and sustainable with no harmful chemicals, meaning it’s 100% baby safe!
  • What does the manufacturer say about breakability? Shatterproof glass is a must, for us.
  • How well does your glass baby bottle withstand hot and cold temperatures? Ensure they can stand the heat of sterilization – like ours can!
  • Does your glass bottle come in different sizes to suit baby’s need for larger feeds as they grow? Consider an option that transforms into a drinking cup or food jar to suit your growing baby’s needs – our Closer to Nature Glass Bottle has a 3-in-1 function that is perfect for this.
  • Is your glass baby bottle shaped to be comfortable in your hand? Our bottles are designed with you in mind, to make your feeding journey as comfortable as possible.
  • Does it have any non-slip features? The best glass bottles are oops proof, spill proof and slip proof!


How to use glass baby bottles

You can use glass baby bottles in the same way that you would use plastic baby bottles. Modern glass baby bottles are made to withstand the odd knock, bump and even drop that comes with family life.

They are more likely to withstand higher temperatures for cleaning and sterilizing, but always follow the manufacturer’s instructions.

If you take care not to drop them from a height onto a hard surface, or crush them, your glass baby bottles should last for the whole of your baby’s feeding journey and beyond.

Are BPA free baby bottles safe?

Many manufacturers, including Tommee Tippee, have removed Bisphenol A (BPA) and Bisphenol S (BPS) from their plastic bottles and other baby feeding items. This is because of concerns about the potentially harmful effects these chemicals can have on babies.

Glass baby bottles are naturally BPA and BPS free, so there are no concerns about the potential harm to baby’s health from using them.
