A gassy baby at 2 a.m. is a specific kind of helpless. If you're searching how to use windi, you've probably got a newborn grunting, squirming, and pulling their legs up, plus a small box of Frida Baby Windi tips you're not sure you dare open. The short version: it's a single-use rectal tube that vents trapped gas, and it works fast when gas really is the problem.
The catch is the margin for error. Manufacturer instructions cap insertion at the built-in flange, and that collar is the only thing standing between a gentle vent and a rectal injury. A pack holds 10 tips, typically $10 to $15 as of 2026.
So before we get to the steps, let's be clear about what this tool is and what it isn't.
How to Use Windi
Wash your hands and unwrap one fresh tip. Lay your baby on their back with knees gently bent. Lubricate the tip with the manufacturer's lubricant and insert it only up to the flange.
Hold it about a minute and let the gas vent out. Discard the tip after a single use.
What Windi Actually Is and What It Won't Fix
The 30-Second Answer
Frida Baby Windi Gas and Colic Reliever is a hollow, flexible, single-use tube with a rounded tip and a depth-limiting flange. The manufacturer markets it as a non-medicated physical device, so there's no drug, herb, or ingredient in play. You insert it briefly, gas escapes through the tube, and you throw it away.
How the Tube Works and Why the Flange Is the Whole Point
The mechanism is mechanical, not chemical. A short insertion past the anal sphincter triggers reflex relaxation, and the hollow bore gives trapped gas somewhere to escape. Per the package instructions, the flange stops the tube at a fixed depth.
That collar is the safety feature. Push past it and you're doing something the device was never designed for.
Gas, Colic, and Constipation Are Three Different Problems
This is where a lot of parents go wrong. Trapped gas is a venting problem. Colic is a behavior pattern affecting roughly one in five infants, usually easing by three to four months, and it has no proven device fix.
Constipation is a stool problem, and Windi is not a laxative. If your baby's belly is firm or they haven't passed stool in days, that's a pediatrician call, not a tube.
What's in the Pack
You get 10 tips, one use each. At current pricing that's roughly $1 to $1.50 per session. Ten sessions disappear fast if you drift into nightly use, which is exactly the habit to avoid.
Before You Unwrap One: Who Shouldn't Use Windi
Hard Stops: Do Not Use If Your Baby Has Any of These
Skip it entirely, and call your pediatrician, if your baby has:
- A fever
- Blood in the stool
- A firm, swollen, or distended belly
- Persistent vomiting, or greenish (bilious) vomit
- An anal fissure, or recent rectal or intestinal surgery
- A diagnosed digestive condition such as Hirschsprung disease
Check With Your Pediatrician First If
Prematurity is the big one. Ask before the first use with any baby born early, and with any newborn under about a month old. Also ask if your baby has feeding trouble, poor weight gain, or a known milk protein allergy.
The American Academy of Pediatrics is a solid starting point for what normal infant gas looks like.
Age, Prematurity, and the Newborn Question
The label covers newborns, but "allowed" and "wise" aren't the same thing. Tiny babies have thinner, more delicate rectal tissue. If you're weighing whether to use it on a two-week-old, get a clinician's sign-off first.
That's not caution theater. Rare case reports of rectal perforation from similar devices exist, and they all trace back to depth and force.
How to Use Windi, Step by Step
Prep: Hands, Lube, and a Calm Baby
Wash your hands properly and unwrap one fresh tip. Use the lubricant the manufacturer supplies or recommends, and don't substitute anything fancy. Calm matters here.
Inserting a tip into a thrashing, screaming infant is how injuries happen.
If your baby is mid-meltdown, stop and settle them first. Bicycle their legs, try a warm bath, give it ten minutes. Then come back.
Positioning and Insertion Depth
- Lay your baby on their back or side, diaper off, knees gently bent toward the belly.
- Rest the tip against the anus, angled toward the tailbone as the instructions describe.
- Insert slowly and stop the moment the flange meets the skin.
- Never push past the flange. Never force against resistance.
Venting, Stopping, and Disposing
Hold the tube in place and let it work. Gas usually vents within seconds, and one minute is the practical ceiling. Withdraw gently at the first sign of blood, pain, or resistance.
Discard the tip in the bin. It's single-use, so there's no cleaning step and no reuse, ever.
What a Normal Result Looks Like
Expect a steady stream of gas and instant relief in a baby who was genuinely gassy. Some babies pass a little stool too, which is normal. What you don't expect is blood, crying that escalates, or a belly that stays hard afterward.
If that happens, stop using it and call your pediatrician the same day.
How Often Is Too Often: Overuse, Dependency, and the Colic Myth
The Real Ceiling on Frequency
Sparingly is the honest answer. The practical guidance is occasional rescue use, not nightly. There's no official daily limit printed on the box, which is exactly why parents drift into overuse.
Treat it like a fire extinguisher. You're glad it's there, but you don't spray it every evening.
Why Babies Can Learn to Need It
Here's the part that rarely gets explained. Passing gas and stool is a skill a baby's body is still learning. Repeated mechanical stimulation can train a baby to rely on the tube for something their gut should eventually do alone.
That's a habit you don't want to build at six weeks old.
Signs You've Crossed From Rescue Tool to Routine
- You're reaching for it more than once a day
- You use it proactively, before fussiness starts
- Your baby seems to need it to pass stool
- You've stopped trying burping, massage, or tummy time first
Any of those? Pull back and talk to your pediatrician about what's actually driving the gas.
Mistakes That Cause Injury, Not Relief
Force and depth cause harm. Reusing a tip risks infection. Leaving it in while you step away is plain unsafe.
And mistaking constipation or reflux for gas means you're treating the wrong problem entirely, which delays real help.
What to Try Before and Instead of Windi
First-Line Moves: Bicycle Legs, Tummy Massage, and Burping
Start here every time. Bicycle your baby's legs, do the "I Love You" tummy massage, and burp properly over the shoulder. Feed in a more upright position with paced bottle feeding.
These are free, zero-risk, and they work often enough that you'll skip the tube most nights.
Windi vs a Rectal Thermometer
| Feature | Windi | Rectal thermometer |
|---|---|---|
| Depth control | Built-in flange | None |
| Designed for gas | Yes | No |
| Single use | Yes | No |
| Best for | Occasional trapped gas | Taking a temperature |
If you need a temperature, use a thermometer. The old nurse's trick of using one to release gas relies on guesswork the flange removes.
Simethicone, Probiotics, and Gripe Water
Simethicone drops merge gas bubbles, though the evidence in infants is thin. Probiotic drops such as L. reuteri may help over weeks, not minutes. Gripe water is loosely regulated and varies wildly by brand.
None of these are equivalent to Windi, and none fix colic either.
Anti-Colic Bottles and Paced Feeding
If gas is a nightly pattern, fix the intake rather than the output. Anti-colic bottles, slower-flow nipples, and paced feeding reduce the air your baby swallows in the first place. The NHS has clear guidance on trapped wind and colic if you want a clinician-reviewed baseline.
When Gas Is a Red Flag: Stop and Call Your Pediatrician
Symptoms That Mean Stop Immediately
Stop the moment you hit resistance, see blood, or your baby's crying changes pitch. Those are the three signals that say something is wrong right now. Withdraw gently, don't reinsert, and don't try again later that night.
Symptoms That Mean Call Today
Call your pediatrician the same day if your baby has a fever, a firm or swollen belly, or greenish vomit. Blood in the stool, no stool for several days, or feeding that's suddenly gone downhill belong on that list too.
Persistent gas that needs venting every single day is a pattern worth investigating. So is poor weight gain, or a baby who screams for hours at the same time each evening. That's the colic picture, and it deserves a proper assessment rather than a nightly tube.
Symptoms That Mean Go to the ER
Go straight to emergency care if your baby's belly is hard and swollen, if they're vomiting green bile, or if they seem limp, pale, or unusually drowsy. Blood that's more than a streak, or any sign of severe pain, means the same. These are not gas symptoms, and no home tool fixes them.
Here's the if/then logic in one place. If gas comes out and your baby settles, you're fine. If nothing comes out and the belly stays tight, stop and call.
If blood, fever, or bile appears at any point, that's emergency territory. Save that list on your phone. At 3 a.m., you won't want to reason it out from scratch.
Frequently Asked Questions
What's the honest bottom line on using Windi?
It's an occasional rescue tool for trapped gas, not a routine. Use it sparingly, stop at the flange, discard the tip after one use, and call your pediatrician if you're reaching for it more than once a day or if anything about your baby worries you.
Can you use Windi on a newborn?
The label covers newborns, but check with your pediatrician first, especially for any baby under one month or born prematurely. Newborn rectal tissue is delicate, and a clinician's sign-off costs you nothing. Never force the tip past the flange at any age.
Does Windi cure colic?
No. It vents gas, and gas is only one possible cause of colic. Colic affects roughly one in five infants and typically eases by three to four months on its own.
If your baby cries for hours most evenings, that's a pediatrician conversation, not a tube problem.
Can you reuse a Windi tip?
Never. Each tip is single-use, and reusing one risks infection. A pack holds 10 tips and costs roughly $10 to $15, so budget for one tip per session and throw it away afterward.
Don't rinse it and set it aside for later.
What if nothing comes out?
Stop and don't push further. If no gas vents and your baby's belly feels firm, or they're vomiting or running a fever, call your pediatrician the same day. Reinserting or pushing deeper won't help and can cause injury instead.
Is Windi safe to use every night?
No, and nightly use is the pattern to avoid. Repeated stimulation can teach a baby to rely on the tube to pass gas or stool. If gas is a nightly issue, fix the intake with paced feeding and anti-colic bottles, and get your pediatrician's input on the bigger picture.
