Flexible (Slim neck) Baby Bottles & Teats

Pigeon Flexible™ s l im neck baby bottles are designed with bottle-fed babies in mind — including smaller infants and premature babies who benefit from a traditional, proportionate bottle shape that's easy to hold and comfortable to feed from.

The Flexible™ range is available in four materials to suit your family's needs. The lightweight Flexible™ PP bottle is a practical everyday option, while the Flexible™ PPSU bottle offers premium-grade durability and high heat resistance for frequent sterilising. For parents who prefer glass, the Flexible™ Glass bottle is non-porous, odour-resistant, and built to last. The Flexible™ T-Ester bottle offers glass-like clarity with the convenience of plastic and is UV steriliser friendly. All bottles are BPA-free and BPS-free.

Every Flexible™ bottle comes with a Peristaltic teat — a slim neck, double-thickness silicone teat with a built-in venting system to help minimise swallowed air and reduce colic. Teats are available across a range of flow rates to suit your baby's age and feeding stage. Read the choosing the right teat flow guide for help selecting the right size, or use the Baby Bottle Selector to find the best fit for your baby.

FAQs about Flexible (Slim neck) Baby Bottles & Teats

What are Pigeon Flexible™ slim neck baby bottles?

Pigeon Flexible™ slim neck baby bottles are a traditional-shaped bottle designed for bottle-fed babies from birth, including smaller and premature infants. The slim neck design is proportionate to smaller hands and mouths, and every bottle comes with a Flexible™ Peristaltic teat — a double-thickness silicone teat with a built-in venting system to help reduce swallowed air and colic. All Flexible™ bottles are BPA-free and BPS-free. A good starting point for newborns is the Flexible™ slim neck baby bottle 120ml.

What materials are the Flexible™ slim neck bottles available in?

The Flexible™ range comes in four materials:

• PP (plastic) — Lightweight and practical for everyday use. The Flexible™ PP 240ml is a popular choice for regular feeds, and is also available as a Flexible™ slim neck twin pack for great value.
• PPSU — Premium-grade and highly heat-resistant, suitable for frequent sterilising. Available in 160ml and 240ml.
• Glass — Non-porous and odour-resistant, with excellent long-term clarity. Available in 120ml and 240ml.
• T-Ester — Glass-like clarity with the convenience of plastic, and unlike standard plastic bottles, is UV steriliser friendly. Available in the Flexible™ T-Ester 250ml.

What is the difference between the Flexible™ and SofTouch™ bottle ranges?

The Flexible™ range features a traditional slim neck design suited to bottle-fed babies, including smaller and premature infants. The SofTouch™ range features a wide neck teat shaped to mimic the natural feel of a mother's breast, and is generally recommended for breastfed babies or those transitioning between breast and bottle. The two teat types are not interchangeable — slim neck teats can only be used with slim neck bottles. For a full comparison, see the wide neck vs standard neck baby bottles guide, or use the Baby Bottle Selector for a personalised recommendation.

What teat sizes are available for Flexible™ slim neck bottles?

Flexible™ Peristaltic teats come in a range of flow rates to suit your baby's age and feeding strength. Replacement teats are sold separately — the Peristaltic Slim Neck Teat S 2pk is suited to younger babies, while the Peristaltic Slim Neck Teat Y 2pk is designed for older babies ready for a faster flow. For guidance on choosing the right size for your baby's stage, read the choosing the right teat flow guide.

Are Flexible™ slim neck bottles good for reducing colic?

Yes. Every Flexible™ bottle features a built-in venting system in the teat that helps regulate air pressure during feeding, minimising the amount of air your baby swallows. This can help reduce discomfort, wind, and fussiness after feeds. For more on how anti-colic bottle design works, see the anti-colic vs regular bottles guide.

Are Flexible™ slim neck bottles suitable for premature or smaller babies?

Yes. The Flexible™ slim neck range is specifically recommended for smaller and premature infants. The compact bottle shape is proportionate to smaller hands, and the Flexible™ 120ml slim neck baby bottle paired with a slow-flow teat is a practical starting point for early feeds. The Flexible™ Glass 120ml is also a popular choice for parents who prefer a non-plastic option from birth.

Can I mix and match Flexible™ teats across different bottles?

Yes — all Flexible™ slim neck bottles are compatible with Flexible™ Peristaltic teats regardless of material, which is useful as your baby grows and their feeding needs change. Just ensure you're using the correct teat size for your baby's current stage. Visit the Baby Bottles & Teats guide for a full breakdown of teat compatibility and sizing.

"Definitely a great drinking cup for daily use. It is compact, lightweight and easy to grip. The bright colours make it more appealing to the little one. I personally found it is easy to take apart and clean. So far we love it!"

I bought it a month ago, seems to work fine. My babies skin is not red anymore. Feels good to use on my baby.

"This bottle is great for my 9 month old. It’s light weight and he is able to independently drink from the bottle. The weighted straw makes it easy for him to drink from all angles."

"I’m a big fan of the liquid cleanser, so I thought I’d give this baby bottle spray a try. It works really well for quick cleans and wipe-downs. Just like the cleanser, it doesn’t leave any chemical smell, and you don’t have to spend ages wiping to make sure everything’s clean."

"I bought this tonight for my 5 mo after trying 5 other brands of bottles and at my wits end. The teat was exactly what I was looking for and he didn’t resist it being given as much as he would the others. Cannot wait to try more and hopefully transition!!! Thank you!"

Why Does My Baby Click, Cough, or Pull Off the Bottle During Feeds?

A clicking sound, a cough, a sudden pull away from the teat. These feeding noises can feel alarming, but most of them trace back to three things: oral seal, teat response and air intake. Here's how to tell what's normal and what your bottle can do about it.
