Parent notes · Night feeds
Fed. Burped. Changed. Still crying at 3am? Why it might not be anything you're doing.
03:14. Third night in a row.
The feed went fine. Full bottle, a good burp, clean nappy. You lay them down, and ten minutes later the legs come up, the fists clench and the crying starts again.
You sit on the floor next to the Moses basket with a cup of tea that went cold two hours ago. Your partner's asleep. And the same question keeps going round your head: what am I doing wrong?
You've tried everything. That's the frustrating part.
If you're reading this, you've probably already been through the list:
- Winding for longer, over the shoulder, on the lap
- Different feeding positions
- Switching formula "in case it doesn't agree with them"
- Gripe water, rocking, the car seat, the hoover sound
- Two or three "anti-colic" bottles that all promised the same thing
Nothing changes, so the guilt grows. But here's what nobody tells you in the first weeks: often the problem isn't the milk, the formula or your technique. It's what happens inside the bottle while your baby drinks.
What actually happens during a feed
When milk flows out of a bottle, something has to flow back in. If air can't get back into the bottle, the pressure inside drops. Some parents call it vacuum shock. Your baby is no longer just drinking. They're pulling against the bottle.
The vacuum builds. The teat can flatten and the flow slows mid-feed.
Your baby breaks the latch to release it, and gulps air along with the next mouthful.
That air goes down into the tummy as trapped wind, and that's often when the fussing starts, well after the feed looks finished.
Every baby is different, and crying can have many causes. If you're worried about your baby's feeding, weight or wellbeing, always speak to your GP or health visitor.
The fix isn't more parts. It's letting the air in.
Most anti-colic bottles try to solve this by adding things: internal tubes, wands, extra inserts. More to scrub at 3am, more to lose down the sink, more seals that can leak.
Bunvia took the opposite route. It's a glass anti-colic bottle with venting designed so air flows into the bottle, not into your baby, so the vacuum doesn't get a chance to build. And it's just three parts.
The Bunvia anti-colic bottle
- Venting designed to help reduce swallowed air
- 3 parts: bottle, collar, teat. No tubes or wands

She latches quickly, drinks calmly, and I'm not constantly stopping to clean up spills. Now car rides feel manageable again instead of something I dread.Hannah W. · Surrey, England
She drinks calmly, there's no constant fuss, and I can finally enjoy being outside with her instead of worrying the whole time. It sounds small, but this bottle gave me my confidence back.Emily R. · Bath, England
