Glass vs Plastic Baby Bottles — Which One Is Best for Your Baby?
When it comes to choosing the right feeding bottle for your baby, the options can feel endless. One of the biggest questions parents face is whether to go for plastic or glass bottles. Both have their own benefits — and understanding the difference can help you make the best choice for your little one (and for you!).
Here’s a simple guide to help you decide 👇
🧩 1. Safety & Material
Plastic bottles are lightweight and easy to handle — especially great for small hands or when you’re on the go. Just make sure they’re BPA, BPS, and phthalate-free. Over time, though, they can scratch or wear down, especially with frequent sterilising.
Glass bottles, on the other hand, are made from natural, chemical-free materials. They don’t leach or absorb odours, and they handle high heat easily — perfect for sterilising or warming milk safely.
✨ Mama tip: If safety and purity are your top priorities, glass is a wonderful choice.
💪 2. Durability
Plastic bottles win when it comes to being drop-proof — they can survive a tumble from almost anywhere.
Glass bottles are sturdier in the long run, but they can break if dropped. Some brands now offer shock-resistant glass or protective silicone sleeves, giving you the best of both worlds.
🧽 3. Cleaning & Maintenance
Glass bottles stay clear, smooth, and easy to clean, even after months of use.
Plastic bottles can cloud over time and may hold onto smells, especially if they’ve been used with formula or warm milk repeatedly.
If you love that freshly washed sparkle, glass bottles make cleaning a breeze.
🚼 4. Weight & Everyday Use
Plastic bottles are lightweight and convenient, perfect for feeding on the go or packing into your diaper bag.
Glass bottles are heavier, so many parents prefer them for home use — where you’re less likely to drop them.
✨ Our tip: Many parents use both! Glass at home, plastic when out and about.
🌡️ 5. Temperature Difference — A Surprising Fact!
Ever noticed that milk in a glass bottle cools down faster than in plastic?
That’s because glass transfers heat much more efficiently. When you touch the bottle, it feels cooler to your hand — and the milk inside actually cools faster, too.
Plastic bottles, being more insulating, keep milk warmer for longer — which can be handy during travel or night feeds.
So, if you often warm milk and want it to stay that way, plastic might work better for you. But if you prefer accurate temperature sensing and quicker cooling, glass is the winner.
🌍 6. Sustainability & Environment
If you’re eco-conscious, glass bottles are the clear choice. They’re 100% recyclable, durable, and long-lasting.
Plastic bottles have improved over the years, but they still have a shorter lifespan and limited recycling options.
Switching to glass can mean less waste — and a smaller footprint for your baby’s future planet. 🌱
⚖️ So, Which Should You Choose?
It really depends on your lifestyle:
Choose Plastic if you want: Lightweight bottles for travel, Shatterproof durability, Slightly warmer milk retention
Choose Glass if you want: Chemical-free and pure material, Easy-to-clean, long-lasting bottles, More eco-friendly, sustainable choice
💡 Best tip: Have a mix of both! Glass bottles at home, and plastic for when you’re out and about.
💬 Final Thoughts
