The Difrax Wide Anti-Colic S-Bottle 310ml is a wide-neck baby bottle built around two of Difrax's signature design features: the curved S-shaped body and an anti-colic valve set into the base. Together they're designed to give a steady, even flow during feeds, so baby can drink at a comfortable pace rather than gulping. It holds up to 310ml and can be used from birth, making it a practical everyday bottle for expressed milk or formula.
Because the S-Bottle is designed to work alongside breastfeeding, it's a useful option if you're combination feeding or introducing a bottle while keeping breastfeeds going. Difrax notes it suits both full-term and premature babies, and the wide opening makes it easy to fill and clean.
How it works
- Anti-colic valve: A patented valve in the base lets air enter from the bottom and mix with the milk. This is designed to reduce the air baby swallows during a feed, which Difrax links to less colic, spitting up and burping.
- Vacuum prevention: The constant supply of air from the base is designed to stop a vacuum forming, so baby can keep drinking steadily without the teat collapsing or the flow stalling.
- S-shaped body: The ergonomic curve is designed to encourage a natural feeding posture for both of you, and to keep the teat filled with milk even when the bottle is nearly empty, so feeds can carry on in the same position from start to finish.
Wide neck and unscrewable base
The wide model has an unscrewable base, which makes it easy to fill — including with cubes of frozen breast milk — and simple to get into for thorough cleaning. The wider body also makes it well suited to milk porridge as baby grows.
Materials
The bottle is made from BPA-free polypropylene (PP), which is lightweight and durable, while the standard S-size teat is soft-coated BPA-free silicone for extra grip and comfort. It's designed and made in the Netherlands.
How to use
Before each use, check that the tiny air hole in the centre of the valve is open by squeezing it several times.
Best For
The Difrax Wide Anti-Colic S-Bottle 310ml is a great option for parents who:
- Want a wide-neck bottle they can use from birth for expressed milk or formula
- Are combination feeding and want a bottle designed to work alongside breastfeeding
- Like the convenience of an unscrewable base for filling and cleaning
- Want a bottle that will carry through to milk porridge as baby moves on to thicker feeds
An anti-colic design describes the intention behind the valve and S-shape; it isn't a guarantee for every baby. If your little one has ongoing feeding discomfort, reflux or colic that concerns you, it's always worth chatting to your clinic sister or healthcare provider.
