You’ve done the research. You bought the highest-rated bottle. You watched every tutorial. And yet, here you are at 3am, with a newborn who is coughing, fussing, falling asleep mid-feed, or flat-out refusing the bottle.
It’s not the bottle’s fault. And it’s not yours either.
Newborn feeding struggles are incredibly common, even when everything else seems “right.” The reality is that feeding is one of the most complex physical tasks a newborn performs. It requires coordination between muscles, reflexes, breathing and stamina that are still developing in those early weeks.
At Pigeon, we hear this story often. A baby who is unsettled at the bottle, taking forever to finish feeds, or seeming uncomfortable, while the parents wonder what they’re doing wrong. Most of the time, the issue isn’t technique or product choice alone. It’s understanding what’s happening developmentally, and matching the feeding setup to where your baby is right now.
This article explains why some newborns struggle with bottles, what’s happening behind the scenes, and how the right approach can make feeding calmer and more comfortable for everyone.
Newborn Reflexes Aren’t Always Feeding-Ready
Babies are born with a set of reflexes designed to support feeding: the rooting reflex (turning towards touch), the sucking reflex (rhythmic sucking when the palate is stimulated), and the swallowing reflex. These reflexes are often described as “automatic,” which can give parents the impression that feeding should be effortless from day one.
But reflexes aren’t the same as skills.
Reflexive sucking is a starting point. Coordinated feeding, where a baby draws milk, swallows safely and breathes in rhythm, is a learned process that takes time to develop. Premature babies, smaller newborns, or those with mild oral differences may take longer to build this coordination, even if their reflexes are technically intact.
According to the Raising Children Network, an Australian Government-funded resource, newborns need time to learn how to coordinate sucking, swallowing and breathing during feeding, and this process varies between babies [1].
Feeding Fatigue Is Real
One of the most overlooked reasons newborns struggle with bottles is stamina. Feeding requires sustained muscular effort from the jaw, tongue, lips and cheeks. For a newborn, this is the physical equivalent of an endurance workout.
When a baby tires during a feed, the signs can be subtle:
• Falling asleep at the bottle before finishing
• Starting feeds well but fading quickly
• Sucking weakly or pausing frequently
• Taking longer than 20–30 minutes per feed consistently
• Waking shortly after feeds, still hungry
Parents often interpret this as a sign of low appetite, sleepiness, or “not liking” the bottle. In many cases, it simply means the baby is working harder than they can sustain, and the feeding setup may be part of the equation.
Research from the Royal Children’s Hospital Melbourne highlights that feeding difficulties in young infants are frequently related to coordination and stamina rather than appetite or willingness [2].
The Flow Factor: When the Teat Doesn’t Match the Baby
Even the best bottle in the world can create problems if the teat flow doesn’t match a baby’s current ability.
Newborns feed using a delicate suck–swallow–breathe rhythm. When milk flow is appropriate, this rhythm stays organised and feeding feels calm. When flow is mismatched, the whole system can be disrupted.
When teat flow is too fast:
• Milk arrives faster than baby can manage safely
• Baby may gulp, cough, splutter, or leak milk
• Feeding feels stressful and baby may pull away or refuse the bottle
• Increased air intake can lead to gas and unsettled behaviour after feeds
When teat flow is too slow:
• Baby has to work excessively hard to draw milk
• The teat may collapse from strong suction
• Fatigue sets in earlier, leading to incomplete feeds
• Feeds take much longer and feel like a battle for both parent and baby
A study published in the American Journal of Speech-Language Pathology found that bottle teat flow rates vary widely across brands and that packaging labels often don’t accurately reflect measured flow [3]. This means a teat labelled “newborn” or “slow flow” in one brand may deliver milk at a very different rate to another.
The takeaway? Watch your baby, not just the label.
It’s Normal, and It Gets Easier
If your newborn is struggling with bottle feeding, the most important thing to know is this: it’s incredibly common, and it doesn’t mean anything is wrong.
Newborns are learning. Their muscles are strengthening. Their coordination is developing. The early days of feeding are often messy, unpredictable and exhausting for baby and parent alike.
What helps most is understanding what your baby is telling you through their feeding cues, and making small adjustments to support them where they are right now:
• Start with an age-appropriate teat flow and observe how your baby responds
• Allow baby to pace the feed. Pauses are normal and healthy
• Try a more upright or semi-reclined feeding position to support swallowing
• If feeds are consistently stressful, consider trying a different flow rate by checking our teat size guide before switching bottles entirely
How SofTouch™ and Flexible™ Bottles Support Newborn Feeding
Pigeon’s SofTouch™ and Flexible™ bottle ranges are designed with newborn feeding coordination in mind.
SofTouch™ Peristaltic PLUS Size SS Teats feature a textured surface that supports latching and ideal tongue positioning. The wide-neck design mirrors the shape of the breast, helping babies who are combining breast and bottle feeding. With an Air Ventilation System (AVS™) to maintain steady milk flow and help reduce colic, and a latch-on line to guide correct positioning, the SofTouch™ range helps support calm, coordinated feeding. Teat sizes range from SS (newborn) through to LLL (15 months+), so flow can be adjusted as baby grows and their stamina increases.
Flexible™ Peristaltic Teat size S are made with double-thickness silicone for softness and flexibility, allowing babies to latch comfortably with minimal effort. Their built-in venting system helps minimise swallowed air and reduce colic symptoms. Available from S (newborn) through to L (9 months+), the Flexible™ range offers a gentle, adaptable feeding experience.
Both ranges are designed to work with your baby’s developing feeding rhythm, not against it.
What Parents Are Saying
Perfect for newborn
"My baby was born a little early and a little bit small but he had no issues with this teat. It's perfect for little babies. It's soft and very easy for baby to use."
— Klaudine German, Flexible™ Peristaltic Teat S 2pcs
Newborn feeding struggles are rarely about the bottle alone. They’re about the complex interplay between reflexes that are still maturing, stamina that’s still building, and flow that needs to match your baby’s current ability.
The “best” bottle is the one that works with your baby’s development, supporting their rhythm, reducing unnecessary effort, and allowing them to feed calmly and comfortably. If something isn’t working, it doesn’t mean you’ve chosen wrong. It often means a small adjustment, particularly to teat flow, can make a significant difference.
Be patient. Watch your baby’s cues. And know that feeding, like everything in those early weeks, is a learning process for both of you.

FAQs
Why is my newborn struggling with the bottle?
Newborn feeding difficulties are common and usually relate to developing coordination between sucking, swallowing and breathing. Stamina limitations and teat flow mismatches can also contribute. It rarely means anything is wrong with your baby.
How do I know if the teat flow is wrong for my baby?
Signs of flow that’s too fast include gulping, coughing, leaking milk and pulling off the teat. Signs of flow that’s too slow include prolonged feeds, strong sucking with few swallows, teat collapse and baby falling asleep before finishing. Watching your baby’s cues is more reliable than the label alone.
Is it normal for newborn feeds to take a long time?
Feed length varies, but consistently long feeds (over 20–30 minutes) combined with fatigue or frustration may indicate a flow mismatch. Reassessing the teat size is a good first step.
Should I switch bottles if my newborn is unsettled during feeds?
Before switching bottles, try adjusting the teat flow rate first. Many feeding difficulties are related to flow rather than the bottle itself. For more guidance, see our article on how air-vented bottles can help a fussy feeder. If problems persist, speak with your child health nurse or paediatrician.
How do Pigeon’s SofTouch™ and Flexible™ bottles help with newborn feeding?
Both ranges are designed to support a natural feeding rhythm with age-appropriate teat flow options, anti-colic venting systems and soft, flexible teats that encourage a comfortable latch. This helps reduce unnecessary fatigue and supports calm, coordinated feeding.
