It’s 3am, the baby is screaming, and the bottle you bought based on a pastel-coloured Instagram ad is leaking warm milk down your arm. The teat flow is too fast, the baby is gulping air, and tomorrow morning you’ll both be paying for it with colic-fuelled crying that could wake the dead.
Choosing the right baby bottle seems like it should be simple — it’s a container with a teat. But any parent who’s been through the 3am bottle lottery knows that the wrong bottle means excess wind, feeding refusal, colic symptoms, and a baby who associates feeding with discomfort. The right one means calm feeds, less wind, and a baby who actually finishes a bottle without a 30-minute screaming intermission.

What Makes a Bottle Anti-Colic
Colic — defined as crying for more than 3 hours a day, more than 3 days a week, for more than 3 weeks — affects up to 40% of babies. While the exact causes are debated, swallowing air during feeding is a well-established contributing factor. Anti-colic bottles reduce the amount of air a baby ingests during a feed.
Venting Systems
The most effective anti-colic bottles use internal venting systems that separate the air flow from the milk flow. As the baby drinks, air enters the bottle through a vent (usually in the base or the teat collar) and bypasses the milk entirely, filling the space behind the milk as it’s consumed. Without venting, the baby has to break suction periodically to let air into the bottle, swallowing bubbles in the process.
Teat Design
Anti-colic teats are designed to maintain consistent flow even as the milk level drops. Some use flexible valves that open under suction pressure. Others have air channels built into the teat itself. The NHS bottle feeding guidance recommends checking that the teat fills with milk (not air) during feeding.
Does Anti-Colic Actually Work?
In practice, the evidence is mixed but parents consistently report less wind, less fussing, and shorter burping sessions with vented bottles compared to standard bottles. It’s not a guarantee — some colicky babies are colicky regardless of the bottle — but reducing air intake can only help.
Best Anti-Colic Bottles
Best Overall: MAM Easy Start Anti-Colic (about £18 for a 3-pack, boots.co.uk)
MAM’s vented base design is clever: air enters through perforations in the bottle base, flowing through a separate channel that keeps it away from the milk. The result is a smooth, bubble-free feed that many parents describe as transformative for colicky babies.
The teats are flat and symmetrical (SkinSoft silicone), designed to feel natural in the baby’s mouth. The bottle self-sterilises in the microwave — unscrew the base, add water, 3 minutes in the microwave, done. No separate steriliser needed. After trying four different bottle brands with our second baby, the MAM was the one that finally stopped the post-feed screaming.
Available at Boots, Amazon UK, and most supermarkets. Replacement teats cost about £5 for a pack of 2.
Best Venting System: Dr Brown’s Options+ (about £22 for a 3-pack, johnlewis.com)
Dr Brown’s pioneered internal venting in baby bottles and their system remains the most thorough. A thin tube runs from the teat collar down into the bottle, channelling air through a series of valves that eliminate all vacuum-related air ingestion. The trade-off is more parts to clean — each bottle has the teat, collar, reservoir, vent insert, and travel disc.
The Options+ range lets you remove the internal venting system as the baby grows, converting it to a standard wide-neck bottle. This dual functionality makes it a good long-term investment. Available at John Lewis, Boots, and Amazon UK.
Best for Severe Colic: Tommee Tippee Advanced Anti-Colic (about £25 for a 3-pack, argos.co.uk)
Tommee Tippee’s advanced system uses a star-shaped valve in the teat combined with a vented tube that draws air away from the milk. The unique heat-sensing strip on the bottle changes colour when the milk is too hot — a simple but brilliant safety feature for exhausted parents making bottles at 4am.
The breast-like teat shape means most babies accept it without protest. Available from Argos, Boots, Tesco, and Amazon UK.
Best Bottles for Breastfed Babies
Switching between breast and bottle is one of the most stressful transitions for new parents. The wrong bottle can cause nipple confusion (where the baby starts preferring the faster, easier bottle flow and refuses the breast) or breast refusal. These bottles are designed to mimic breastfeeding as closely as possible.
Best for Combination Feeding: Medela Calma (about £12 for a single bottle, medela.co.uk)
The Calma teat only releases milk when the baby actively sucks — exactly like breastfeeding. There’s no drip, no passive flow. The baby has to work for the milk in the same way they do at the breast, which maintains their breastfeeding technique. Lactation consultants consistently recommend Calma for combination-feeding mothers.
The downside: some babies find it frustrating if they’re already used to faster-flowing conventional teats. Introduce it before the baby learns that bottles = easy milk.
Best Teat Shape: Lansinoh mOmma (about £8 per bottle, lansinoh.co.uk)
Lansinoh’s NaturalWave teat is designed with input from breastfeeding researchers. The flexible teat mimics the natural movement of the nipple during breastfeeding — it stretches, compresses, and flexes in response to the baby’s mouth movements. The air ventilation system reduces colic risk while maintaining the natural feeding rhythm. Understanding sterilisation methods is especially important when combination feeding, as breast milk and formula have different bacterial profiles.
Best Mainstream: Tommee Tippee Closer to Nature (about £15 for a 3-pack, tesco.com)
The UK’s best-selling baby bottle for over a decade. The breast-shaped teat and flexible silicone mimic the natural feel of breastfeeding well enough that most babies switch between breast and this bottle without issues. Not as sophisticated as the Medela Calma or Lansinoh, but vastly more practical — affordable, widely available, and accepted by the majority of babies.
Best Budget Bottles
Tesco Fred & Flo (about £3 for a 3-pack)
Surprisingly good for the price. Standard anti-colic venting, clear markings, compatible with most standard sterilisers. They lack the premium venting of MAM or Dr Brown’s, but for parents on a tight budget, three bottles for £3 is hard to argue with. Available at Tesco stores and online.
ASDA Little Angels (about £4 for a 3-pack)
Similar quality to Fred & Flo with slightly softer teats. The anti-colic valve is basic but functional. The main advantage is availability — ASDA has them in every store.
Are Budget Bottles Safe?
All baby bottles sold in the UK must be BPA-free and meet BS EN 14350 safety standards regardless of price. A £3 bottle is as safe as a £12 bottle. The differences are in anti-colic effectiveness, teat quality, and durability — not safety.
Bottle Materials: Plastic vs Glass vs Silicone
Polypropylene (PP) Plastic
The standard material for most baby bottles. Lightweight, shatterproof, cheap, and BPA-free (since 2011, all UK baby bottles must be BPA-free by law). The downside is scratching over time — scratched bottles can harbour bacteria in the grooves. Replace plastic bottles every 3-4 months or when visibly scratched.
Glass
Glass bottles don’t scratch, don’t absorb odours, and can be sterilised at higher temperatures. They last indefinitely. The obvious downside is weight and breakability — a dropped glass bottle on a tile floor is a hazard with a crawling baby. MAM and Dr Brown’s both make glass versions of their popular bottles (about £8-10 per bottle). Best used at home rather than on the go.
Silicone
A relatively new option. Silicone bottles (like the Comotomo, about £12 per bottle from Amazon UK) are soft, squeezable, and feel more natural in the baby’s hand. They don’t scratch like plastic or break like glass. The soft body mimics the feel of a breast, which some babies respond well to. The downside is price and limited availability in UK shops.
Teat Shapes and Flow Rates
Teat Shapes
- Round/cherry-shaped — traditional shape. Simple, works for most babies. Used by Tommee Tippee Closer to Nature.
- Flat/orthodontic — designed to sit flat against the palate, supporting natural mouth development. Used by MAM and NUK.
- Wide-neck/breast-shaped — broader base mimicking the breast. Easier latch for breastfed babies switching to bottles.
- Elongated — longer teat that reaches further into the mouth. Some babies prefer the deeper positioning.
Flow Rates
- Newborn/Size 1 (0-3 months) — slow flow. A full feed takes 15-20 minutes. Start here.
- Size 2 (3-6 months) — medium flow. Feeds take 10-15 minutes.
- Size 3 (6+ months) — fast flow. Feeds take 5-10 minutes.
- Variable flow — the baby controls the flow speed by their sucking strength. Good for babies who get frustrated with fixed-flow teats.
Move up a teat size when feeds consistently take longer than 20 minutes, the baby falls asleep mid-feed from effort, or the teat collapses inward during feeding.
How Many Bottles Do You Need
Formula-Fed Babies
Six to eight bottles covers a full day with enough spares for sterilising cycles. A newborn feeds 8-12 times per day, so you’ll cycle through bottles quickly. Having 8 means you can sterilise in batches rather than washing and sterilising one bottle at a time between feeds.
Combination-Fed Babies
Three to four bottles is enough if you’re supplementing breastfeeding with occasional bottles. One or two feeds a day from a bottle means less washing and fewer bottles sitting around.
Exclusively Breastfed Babies Taking Occasional Bottles
One or two is sufficient. These are for the odd expressed milk feed when you’re out, or for a partner to do a night feed.
Sterilising and Cleaning
Bottle Cleaning
- Wash immediately after use — milk residue hardens fast and becomes much harder to remove
- Use a bottle brush that reaches the bottom and cleans the internal curves. Silicone brushes are gentler on plastic than bristle brushes.
- Clean the teat inside and out — milk can collect in the valve holes. A teat brush (about £3 from Boots) makes this easier.
- Use hot soapy water — washing-up liquid is fine. Rinse thoroughly.
Sterilising Methods
The NHS recommends sterilising all feeding equipment until your baby is at least 12 months old. Methods include:
- Microwave steam steriliser — 3-5 minutes. The most popular method. About £15-25 for the steriliser.
- Electric steam steriliser — 8-12 minutes. Holds more bottles. About £25-50.
- Cold water sterilising solution — Milton tablets in a container of water, 15-30 minutes. About £3 for 28 tablets. No electricity needed.
- Boiling — fully submerge in boiling water for 10 minutes. Free but labour-intensive and shortens the life of plastic bottles.
Switching Between Breast and Bottle
When to Introduce a Bottle
Most breastfeeding experts and the La Leche League recommend waiting until breastfeeding is well established (typically 4-6 weeks) before introducing a bottle. Introducing too early can cause nipple confusion; too late and some babies refuse the bottle entirely because they’ve never encountered one.
Tips for a Smooth Transition
- Let someone else give the first bottle — the baby associates you with the breast. Having a partner or grandparent offer the bottle reduces confusion.
- Use expressed breast milk first — familiar taste in an unfamiliar container is less jarring than formula in an unfamiliar container.
- Choose a slow-flow teat — a fast flow makes the bottle too easy compared to the breast, which can cause breast refusal.
- Try paced bottle feeding — hold the baby upright, keep the bottle horizontal, and pause every few minutes. This mimics the pace of breastfeeding rather than the continuous flow of a tilted bottle.
- Don’t force it — if the baby refuses, stop and try again in a few hours. Forcing a bottle creates negative associations.
Frequently Asked Questions
What is the best anti-colic bottle for newborns? The MAM Easy Start Anti-Colic is our top pick for newborns. The vented base eliminates air ingestion, the self-sterilising feature is a lifesaver at 3am, and the SkinSoft teat is accepted by most babies. Dr Brown’s Options+ is the best alternative if the MAM teat shape doesn’t suit your baby.
How do I know if my baby needs anti-colic bottles? Signs include excessive crying after feeds, pulling legs up to the chest, arching the back during feeding, excessive wind, and difficulty settling after eating. If your baby feeds calmly and burps easily with standard bottles, you may not need anti-colic versions. Try one anti-colic bottle before buying a full set.
Can I mix bottle brands? Yes — there’s no reason to stick with one brand. Many parents find that their baby prefers one brand’s teat but another brand’s bottle body. Teats are generally not interchangeable between brands (different neck sizes), but you can use different brands for different feeds without any issues.
When should I replace baby bottles? Replace plastic bottles every 3-4 months or when visibly scratched, cloudy, or discoloured. Replace teats every 2-3 months or immediately if you notice any tears, cracks, or changes in shape. Glass bottles can be used indefinitely as long as they’re not chipped or cracked.
Are expensive bottles worth it? For colicky babies, the anti-colic venting in premium bottles (MAM, Dr Brown’s) can make a real difference to feeding comfort. For non-colicky babies, budget bottles from supermarket own-brands are perfectly adequate. Start with a single premium bottle to test before committing to a full set.
