Are Philips Avent Natural Glass Bottles Worth It?
Worth it, if pacing and durability matter more than weight

Worth it if you're pacing feeds to match breastfeeding, not just buying a bottle

Picture the moment your baby unlatches from a bottle gasping, milk dribbling from the corner of their mouth, gulping faster than they can keep up with. You wonder whether a different nipple, or a slower flow, would help, especially if you're moving between breast and bottle and don't want your baby getting confused about how to feed. Philips Avent's natural glass bottles are built around exactly that worry.
Here's the clever bit: the Natural Response nipple doesn't let milk trickle through on its own, it only opens when your baby actively sucks, the same way milk only flows from the breast when a baby is working for it. That's what lets your baby set the pace, pause for a breath, and self-regulate intake, instead of the bottle dumping milk into their mouth on a fixed drip. The nipple's shape helps too: it's wide and soft like a breast rather than a narrow spout, so babies moving between breast and bottle don't have to relearn how to latch. Meanwhile the anti-colic valve does quieter work, channeling air away from the tip and into the bottle instead of down with the milk, which is the difference between a baby who feeds and settles and one who feeds and then squirms with trapped air. And because the bottle is borosilicate glass rather than plastic, it goes from fridge to warm water without cracking, and survives repeated sterilizing without clouding, scratching, or holding onto old milk smells the way plastic eventually does.
So you're not really buying a bottle, you're buying a feeding rhythm, one that matches what your baby already knows from the breast, so swapping between the two doesn't throw off their pacing or their patience. The glass is really just the bonus, it happens to be the material that survives the fridge, the warmer, and the sterilizer without wearing out.
Worth it if
- You're moving between breastfeeding and bottle feeding and want the pacing to match
- You want a bottle material that won't scratch, cloud, or hold smells after repeated sterilizing
- You're fine with glass's weight and care in exchange for durability
Skip it if
- You need the lightest option for daycare or overnight feeds
- You're wary of handling glass while groggy at 3am
- You just want a basic bottle and don't care about breast/bottle pacing
If you're combination feeding, or breastfeeding and want a bottle that won't undo the pacing your baby's used to, this is a quiet yes, and the glass will outlast the plastic bottles you'd otherwise keep replacing. If you mostly need something light for daycare drop-offs or groggy overnight feeds, where dropped glass is a real risk, a plastic version of the same nipple gets you the same pacing without the weight.
