Flexible (Slim neck) Baby Bottles & Teats

Flexible (Slim neck) Baby Bottles & Teats

Pigeon Flexible™ slim neck baby bottles are specifically designed for bottle-fed babies and smaller infants, including premature babies and those with lower birth weights. The compact, traditional bottle shape and narrower opening are proportionate to smaller hands and mouths, making feeding more comfortable and manageable for babies who need a gentle, tailored approach.

If your baby has been bottle-fed from birth or is smaller than average, the Flexible™ range is purpose-built for their needs. The lightweight, easy-to-grip design is ideal for babies who may struggle with larger, wider bottles. The narrow neck means less bottle to manage during feeds, reducing fatigue for both baby and parent.

Each Flexible™ bottle is paired with soft, flexible silicone teats that support your baby's natural suckling pattern. The double-thickness silicone provides ideal softness for comfortable latching, whilst Pigeon's unique venting system minimises swallowed air and helps reduce colic, gas, and fussiness, which is particularly important for smaller babies with developing digestive systems.

Available in four premium materials:

Polypropylene (PP)
PPSU
Glass
T-Ester

The Flexible™ range offers flexibility for different feeding needs and preferences. All bottles come with teat options in multiple flow rates (slow, medium, fast, and variable) to match your baby's age, size, and feeding stage.

Whether you're exclusively bottle-feeding, have a smaller or premature baby, or simply prefer a traditional bottle shape with reliable anti-colic performance, Pigeon Flexible™ slim neck bottles deliver trusted, comfortable feeding designed specifically for bottle-fed and smaller infants.

FAQs about Flexible (Slim neck) Baby Bottles & Teats

Why is the Flexible™ slim neck range recommended for bottle-fed and smaller babies?

The Flexible™ slim neck range is specifically engineered for bottle-fed babies and smaller infants. Here's why it's the ideal choice:

• Proportionate bottle size: The compact design and narrower opening match the proportions of smaller mouths and hands, making it easier for your baby to latch and hold the bottle comfortably
• Less overwhelming: Bottle-fed babies benefit from a bottle that feels manageable rather than oversized, reducing feeding stress and fatigue
• Lightweight design: The slim neck bottles are noticeably lighter than wide-neck alternatives, making them ideal for smaller babies who may tire easily during feeds
• Designed for bottle-fed babies: Unlike wide-neck bottles designed to mimic breastfeeding, Flexible™ bottles acknowledge and support the unique feeding experience of exclusively bottle-fed infants
• Smaller teat sizes: Flexible™ teats in slow-flow (S) are particularly suitable for smaller babies and premature infants with developing sucking strength

If your baby is smaller than average, premature, or has been bottle-fed from birth, Flexible™ is the range built specifically for them.

How do the anti-colic teats work on Flexible™ bottles?

Flexible™ bottles feature Pigeon's unique anti-colic venting system built into the bottle design. This system is especially beneficial for smaller and premature babies whose digestive systems are still developing:

• Reducing air intake: The venting allows air to enter the bottle rather than being swallowed by your baby, which significantly reduces the amount of air in their stomach
• Minimising swallowed air: Less air intake means fewer windups, less gas, and reduced discomfort—critical for smaller babies who may struggle with digestive sensitivity
• Supporting comfortable feeding: Combined with soft, flexible teats, the anti-colic system helps even the smallest babies feed more calmly and contentedly

The soft, double-thickness silicone teats also encourage natural suckling patterns, which further supports gentle, comfortable feeding without gulping or choking that could increase air intake—particularly important for smaller infants with developing feeding skills.

What teat flow rates are available, and when should I switch sizes?

Flexible™ bottles come with Flexible Peristaltic teats in multiple flow rates specifically to support smaller babies as they grow:

• S (slow flow): For newborns and smaller babies (0–3 months) with developing sucking strength. Particularly essential for premature babies and smaller infants who need extra time and support during feeds
• M (medium flow): For babies 3–6 months becoming more efficient feeders, or for smaller babies progressing in feeding strength
• Y (variable flow): Adapts to your baby's sucking rhythm for flexible feeding, ideal for babies with inconsistent sucking patterns
• L (fast flow): For older babies and toddlers (6+ months) with stronger sucking power

Watch for signs your baby is ready to progress: taking too long to feed (may need faster flow), choking or gulping (may need slower flow), or showing frustration during feeds (may indicate a mismatch). For smaller and premature babies, progress at their pace—developmental age may differ from chronological age, so follow your baby's cues rather than strictly by calendar age.

Are Flexible™ slim neck bottles easy to clean and sterilise?

Yes, absolutely. The slim neck design is straightforward to clean and sterilise, making daily feeding management simpler for busy parents of smaller babies:

• Narrow opening: Compatible with most bottle brushes, making hand washing easier and faster
• Durable materials: PP, PPSU, glass, and T-Ester all withstand boiling, steam sterilisation, and UV sterilisation without degradation
• Component compatibility: Slim neck bottles work with a wider range of sterilisers and bottle warmers than some other styles, giving you more flexibility in sterilisation methods
• Easy disassembly: Teats and caps come apart easily for thorough cleaning of all components

Always follow the specific care instructions for your chosen material. For example, glass bottles benefit from extra care to avoid chipping, while PPSU bottles are particularly heat-resistant.

Can I mix and match Flexible™ teat sizes across different bottles?

Yes! All Flexible™ slim neck bottles are compatible with Flexible Peristaltic teats, which is especially helpful when feeding smaller babies who may need different teats at different times:

• Use different teat sizes with the same bottle as your baby grows and feeding strength develops
• Mix and match teats across your collection of Flexible™ bottles for flexibility and convenience
• Try different flow rates to find what works best for your smaller baby's unique feeding needs

This compatibility means you can build a feeding system specifically tailored to your smaller baby's progression, without needing to replace entire bottles. Buy replacement teats individually as needed.

Is the Flexible™ slim neck bottle good for exclusively bottle-fed babies?

Absolutely—the Flexible™ range is specifically designed for bottle-fed babies. Here's why it's the perfect choice for exclusive bottle feeding:

• Built for bottle feeding: Unlike wide-neck SofTouch™ bottles designed to support breastfeeding transitions, Flexible™ is purpose-built for babies who are exclusively bottle-fed from birth
• Compact, familiar shape: The traditional bottle form is the natural choice for bottle-fed babies with no breastfeeding experience to reference
• Soft, flexible teats: The double-thickness silicone teats are gentle and soft, providing a comfortable, supported feeding experience specifically for bottle-fed infants
• Anti-colic support: The venting system reduces air intake, helping avoid digestive discomfort common in bottle-fed babies
• Proportionate design: The compact size is ideal for smaller bottle-fed babies and premature infants

If you're exclusively bottle feeding—whether from choice, necessity, or because your baby is smaller or premature—Flexible™ slim neck is the range designed specifically for your feeding journey.

"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!"
