Two Sizes, One System: What Sets Them Apart
BIBS offers two baby glass bottle sets: the 120ml set and the 240ml set. Both are made from borosilicate glass, which is temperature- and thermal-shock resistant, and come with a slow-flow natural rubber latex nipple and an anti-colic valve. The key difference is the bottle volume: the 120ml set holds 110 ml (approximately 4 oz), while the 240ml set holds 225 ml. This size difference affects how long the bottle will suit your baby as they grow and how it fits into your feeding routine.
120ml vs 240ml: Key Differences at a Glance
The two sets share the same material, nipple type, and anti-colic design, but differ in volume and included nipple flow. Here's how they compare:
- Bottle Volume: The 120ml set holds 110 ml; the 240ml set holds 225 ml. The larger bottle can accommodate more milk or formula for older babies or longer feeds.
- Included Nipple Flow: Both sets come with a slow-flow nipple suitable for younger babies. The 240ml set is also available with a medium-flow option, which may be useful as your baby's feeding skills develop.
- Set Contents: Each set includes two bottles, two nipples (slow flow), caps, screwcaps, milk locks, and foldable funnels. The milk lock allows spill-free storage on the go.
- Nipple Material: Both use natural rubber latex nipples with an anti-colic valve. Note that natural rubber latex may show color variation, and some babies may prefer silicone (available separately).

How to Decide Based on Your Baby's Stage
If your baby is very young or takes small feeds, the 120ml set is a practical starting point. Its compact size is easy to handle and clean. As your baby grows and begins to take larger amounts, the 240ml set reduces the need for refills during a feed. You can also buy extra nipples in different flows separately, so you're not locked into one flow rate if you choose the 120ml set. The Mix & Match concept lets you combine bottle parts in your preferred colors, so you can add a 240ml bottle later without buying a whole new set.
Material and Safety Considerations
Both sets are made from borosilicate glass, which does not emit microplastics into the milk. All parts are 100% safe food-grade material, and the bottles comply with European standards EN 1400+A2, EN 14350, and others. The anti-colic valve in the nipple reduces air swallowed during feeding. For cleaning, follow the manufacturer's guidelines; the supplied information does not specify dishwasher or sterilizer compatibility, so hand washing and steam sterilization are recommended unless confirmed otherwise.
