Finding the perfect bottle for your baby can be overwhelming, but the Difrax S-bottle stands out as a game-changer for both parents and professionals. More than 80% of birth care specialists in the Netherlands recommend it to new families, and for good reason. It’s designed to reduce colic, support a baby’s natural sucking reflex, and work seamlessly alongside breastfeeding. With a thoughtfully engineered shape and medical backing, the S-bottle is redefining the bottle-feeding experience.
Parents who choose the Difrax S-bottle see the difference almost immediately. 78% report fewer colic cramps*, thanks to its innovative anti-colic design that minimises air ingestion and prevents discomfort. With nearly half of Dutch parents already trusting the Difrax S-bottle, and both families and professionals rating it 8/10 for performance and ease of use*, it’s clear that this bottle isn’t just another option, it’s a proven solution.
* The figures quoted are based on consumer research conducted by WIJ Special Media amongst 1886 participants and an online survey conducted by Difrax BV at verloskundigenloket.nl and kraamzorgloket.nl. More than 160 maternity nurses and 100 obstetricians took part in the research.
The Difrax S-Bottle: A Smart, Anti-Colic Solution for Happier, Healthier Feeding
The Magic of the S-Bottles
The Spectra S1 comes with a 3-hour rechargeable battery, providing approximately 4-6 unplugged pumping sessions, making it ideal for those longer outings. In comparison, the Spectra Dual Compact has a 2-hour rechargeable battery, offering around 2-4 unplugged sessions. While both pumps are designed for portability, the Spectra Dual Compact has the added convenience of a USB Type-C charger, allowing you to easily charge it on the go with a power bank. This is a feature the Spectra S1 lacks, as it requires its own unique charger and needs to be plugged into a wall outlet for charging.
Both models also include a smart auto-off function, which turns off the pump after 30 minutes of use. This feature not only helps you track your pumping time but also prevents the battery from draining unnecessarily, avoiding situations where you might accidentally leave the pump running in your bag and find it dead later.
S-Shape & Anti-Colic Base
The Difrax S-bottles curved body isn’t just for looks, its distinctive S-shape plays a crucial role in making bottle-feeding smoother and more comfortable for babies. Designed in collaboration with medical specialists, this shape ensures a steady, uninterrupted flow of milk, significantly reducing the chances of air bubbles forming in the feed. Unlike traditional bottles where air can mix with the milk, the Difrax bottle features an anti-colic valve at the base, directing air away from the feed so that babies ingest as little air as possible. This can make a significant difference in preventing discomfort and reducing the likelihood of colic and digestive issues.
The anti-colic valve is essential in preventing a vacuum from forming inside the bottle, ensuring that milk flows freely without interruption.
In bottles without a valve, the suction from the baby can cause a vacuum effect, making it harder for milk to come through consistently. Difrax’s solution is a durable, 100% silicone valve positioned at the base of the bottle, allowing air to circulate above the feed without affecting the milk itself. This helps maintain an even flow, reducing the risk of swallowing air.
Another major benefit of the S-shape is that it naturally supports a more ergonomic feeding position, closely resembling the way babies are positioned during breastfeeding. This not only makes the experience feel more natural for the baby but also provides better posture and comfort for parents while feeding. Additionally, the teat remains filled with milk throughout the feed, even when using smaller amounts of liquid, reducing the likelihood of air ingestion. The anti-colic valve and the unique S-shape prevent the mixing of air and milk, which reduces the risk of colic and preserves essential nutrients, including vitamins A, C and E.
Practicality is also a key feature of the Difrax S-bottle, as the base can be unscrewed for easy filling and cleaning. This larger opening at the bottom makes it convenient to prepare formula, pour in milk, or thoroughly clean the bottle after use. Whether for convenience, comfort, or reducing colic symptoms, the S-bottle’s unique design offers a carefully thought-out solution that enhances the bottle feeding experience.
Bottle Material
The Difrax S-bottle are made of polypropylene. Polypropylene (PP) is a fully recyclable, BPA-free plastic, making it a safe and practical choice for feeding. It is designed to withstand large temperature differences, meaning it won’t warp or degrade easily when exposed to heat or cold. This material is also resistant to bacteria and fungi, ensuring long-term hygiene, and can be safely steam sterilised for easy cleaning.
Both Slim & Wide Neck Design
The Difrax S-bottle is designed to cater to different feeding preferences with both slim and wide neck options, ensuring a comfortable feeding experience for every baby. The Natural S-Bottle, with its slim design and smaller teat, is a popular choice as it is easy to hold and well-suited for babies who naturally accept a narrower bottle shape. Available in 170ml and 250ml, it provides flexibility for both newborns and growing babies. The smaller 170ml size is ideal for newborns and smaller feeds, while the larger 250ml bottle accommodates increased feeding volumes as babies grow.
For babies who prefer a wider latch, the Wide S-Bottle offers a larger, more breast-like teat. This design is ideal for infants who tend to open their mouths wider during feeding, making the transition between breast and bottle feeding smoother. In South Africa, the Wide S-Bottle is available in a 200ml size, providing a good starting option for parents who want to encourage a broader latch from the beginning.
Larger bottles also come with small teats, so if you already know your baby likes the Difrax S-Bottle, you can save money by skipping the smaller size and going straight for the larger bottle. This way, you won’t have to replace the bottle as your baby’s intake increases—just swap out the teat when needed.
The Magic of Difrax S-Bottle Teats
The innovation doesn’t stop at the bottle itself! Difrax teats are just as thoughtfully designed to cater to babies of all ages and feeding needs, from premature newborns to toddlers 12 months and older. With multiple shapes, flow rates, and specialised options, there’s a perfect fit for every baby, whether they need a gentle, slow flow or a wider latch for a more natural feeding experience.
Made from high-quality, odourless, and tasteless silicone, all Difrax teats are designed for safety, comfort, and easy acceptance. Their smooth finish allows them to glide effortlessly in and out of your baby’s mouth, while the soft coating on the Natural and Wide bottle teats provides extra grip, ensuring a secure and comfortable latch every time.
Natural Bottle Teat
he Natural bottle teat is shaped like a mother’s nipple while breastfeeding, making it easy for babies to accept. This design is ideal for parents who want to combine breastfeeding with bottle feeding, as the familiar shape promotes a smooth transition between breast and bottle. The soft coating adds extra grip, ensuring that babies can latch on securely without slipping. These teats are specifically designed to fit the Natural S-bottles, available in both 170ml and 250ml sizes.
The Natural teat comes in multiple flow sizes, each suited to a different stage of your baby’s development:
- S (Small) – Standard teat included with Difrax Natural S-bottles, suitable for newborns from birth (0+ months). This slow flow rate is ideal for breastfed babies, newborns, and babies who need a gentle, controlled flow to avoid overfeeding or choking.
- M (Medium) – Suitable for babies from around 3 months old who need a slightly faster flow. This is a good option for babies who are starting to drink more confidently but still need a controlled flow.
- L (Large) – Best suited for babies 6 months and older, or for those who have stronger suction power and are consuming thicker milk feeds. This is ideal for parents who use thicker formulas or milk with added cereals, as it allows for a smooth, uninterrupted flow.
Difrax Dental Teat
The Dental bottle teat is designed for babies who experience feeding challenges, such as reflux, choking easily, drinking too quickly, or being born prematurely. Its flat-sided design helps to evenly distribute milk in the baby’s mouth, ensuring better control over the flow and reducing the risk of choking. By allowing milk to spread evenly across the tongue, it promotes proper swallowing and digestion, making feeding more comfortable and manageable.
This teat is only available in a Small (S) flow rate, making it ideal for newborns and young babies who require a gentle and controlled flow. The Dental teat is exclusively designed for Natural S-bottles, fitting both the 170ml and 250ml sizes.
Difrax Wide Bottle Teat
The Wide bottle teat is designed for babies who prefer a wider latch, similar to how they latch onto the breast while breastfeeding. The wide base of the teat mimics the natural shape of the breast, making it an excellent option for babies who are breastfed and transitioning to a bottle. This familiar shape can help with acceptance, ensuring a smoother transition between breast and bottle feeding.
These teats are exclusively compatible with the Difrax Anti-Colic Wide S-bottles, which are available in 200ml.
The Wide bottle teat comes in multiple flow sizes to accommodate different feeding needs:
- Small (S): Suitable from birth (0+ months) for babies who drink at an average pace.
- Medium (M): Recommended for babies around 3 months old or when the Small size becomes too slow for their feeding needs.
- Large (L): Ideal for babies 3 months and older, particularly for those who need a faster flow. It is also suitable for thicker feeds, such as milk porridge or thickened formulas.
Difrax 1-2-3 Ring with Variflow Teat
The Difrax Variflow Teats give parents more control over feeding flow, allowing you to adjust the speed without needing to change teats. Both the XS Variflow Teat Natural and 1-2-3 Variflow Teat Natural use the Difrax 1-2-3 Ring, with three adjustable flow settings selected by positioning the corresponding marker under your baby’s nose.
* | Single line: Slowest flow
* || Double line: Medium flow
* ||| Triple line: Fastest flow
The XS Variflow Teat Natural is designed for newborns, premature babies and babies who need a particularly slow, controlled flow. Its three settings range from XXS → XS → S, allowing you to gradually increase the flow as your baby becomes more comfortable with feeding.
The 1-2-3 Variflow Teat Natural is designed for babies from around 3 months and offers a faster range of flows. The three settings progress from a small opening for thinner liquids, to a medium opening for slightly thicker feeds, and finally a larger opening for thicker feeds.
Both teats feature Difrax’s adjustable flow system, so you can choose the setting that best matches your baby’s feeding ability and the consistency of their feed. This means you can fine-tune the flow as your baby grows without necessarily needing to change teats.
Both Variflow teats are compatible with the Difrax S-bottle Natural in both 170 ml and 250 ml sizes.
