The Windi is a soft single-use vent tube with a stopper, sold by Frida Baby for trapped gas in babies. It contains no medicine, carries no Drug Facts panel, and it is not a laxative. Bought for the right problem it is one of the few genuinely useful things on the baby shelf. Bought for constipation it will disappoint you, which is why half this review is about telling the two apart. The 20 count box at $24.92 is about $1.25 per Windi. Prices verified via the Amazon Creators API on September 5, 2026.

Buy the Frida Baby Windi Gas Passer, 20 count, at $24.92 (verified via the Amazon Creators API on September 5, 2026), which is about $1.25 per Windi and the only listing in the range that publishes a count, so the only one whose cost per use can be computed honestly. The smaller box at $12.74 is the cheaper way to find out whether it suits your baby, and the Fart Freeing Essentials bundle at $19.99 adds a belly rub for massage.
The Windi is a short, soft, single-use tube with a stopper that limits how far it can be inserted, designed to help a baby release trapped gas. It is a device rather than a medicine: no active ingredient, no Drug Facts panel, nothing absorbed, and no interaction with anything else your baby is given. That simplicity is the whole appeal, and it is why parents who are uneasy about giving a newborn a drug or a supplement will often try this first.
It is also the product most likely to be bought for the wrong problem on this entire site. Gas and constipation produce an almost identical performance from a baby, straining, red face, knees drawn up, unhappy crying, and the Windi addresses one of them. If your baby's stools are normal in consistency and frequency, gas is the likely story and this is the tool. If stools are hard, pellet-like, or noticeably less frequent than that baby's own pattern, this will not help, and that belongs on the constipation shelf and, under age 2, in a phone call. We are a research and verification desk, not clinicians, nothing here is medical advice, no brand paid for a placement, and if you buy through a link we may earn an Amazon commission at no cost to you.
The short version
- Our Pick: the Windi 20 count at $24.92, about $1.25 per use, and the only listing that publishes a count.
- The Windi is for trapped gas. It is not a laxative, it makes no laxative claim, and it does nothing for hard or infrequent stools.
- It is a device, not a drug or a supplement: nothing absorbed, no Drug Facts panel, no interactions.
- Single use is the real cost. At about $1.25 each the spend continues for as long as the problem does, which is the honest downside.
- If the problem is constipation and the child is under 2, every laxative label sends you to a doctor first. Start with a call, not a purchase.

Frida Baby Windi Gas Passer, 20 count
Frida Baby
Twenty single-use vent tubes at about $1.25 each, the only listing with a published count.
Our verdict: The box to buy once you know the Windi suits your baby, and the only one in the range whose price can be judged, because it is the only listing that publishes a count. Twenty single-use tubes at about $1.25 each is not cheap, and gas is a recurring problem in the early months, so the arithmetic matters more here than on most baby products.
Verified: Frida Baby Windi Gas Passer, baby gas relief for babies and infants, 20 count per the listing title. A single-use device with no active ingredient and no Drug Facts panel. Live at $24.92 on Amazon, verified via the Creators API on September 5, 2026, about $1.25 per Windi.
What you are actually buying. The Windi 20 count is twenty short, soft, single-use tubes with a stopper that limits insertion depth, at $24.92, about $1.25 each. There is no medicine in it and no Drug Facts panel on it. It is a mechanical tool, and the reason it earns a place on a site about suppositories is that it is inserted the same way and gets bought by the same worried parent at the same hour.
On value, the count is the point. This is the only Windi listing that publishes one, so it is the only place a real cost per use can be worked out, and $1.25 a time is the number to plan around. The smaller box at $12.74 does not publish its count, so we compute nothing for it, and the bundle does not either.
What it will not do is help a constipated baby. That shelf is baby constipation relief, and under age 2 it starts with a call. If you want the full picture of what is labeled for what at each age, suppositories for babies and toddlers collects every age line in one place.
Who should buy it
Buy the 20 count if you already know the Windi works for your baby and you would rather not reorder every fortnight. It is the sensible box for the months when gas is a recurring evening problem.
What we don't like
About $1.25 every single time, forever, because there is nothing reusable in the design. Twenty units is a $24.92 commitment to a product you may find you do not want to use, and it does nothing at all for hard stool.

- Count
- 20

- Label ages
- Marketed for babies and infants; follow the packaging guidance
- Cost per use
- $1.25 ($24.92 divided by 20)

What we like
- The only Windi listing that publishes a count, so the only computable value
- Contains nothing, so nothing is absorbed and nothing interacts
- The stopper takes the depth decision away from a nervous parent
- Single use and sealed, with nothing to clean or sterilise
Worth noting
- About $1.25 per use, with no reusable component
- $24.92 up front before you know whether it suits your baby
- For gas only; useless for hard or infrequent stools
Frida Baby Windi Gas Passer
Frida Baby
The smaller box at $12.74, the low-risk way to find out if it suits you.
Our verdict: The right first purchase, because plenty of parents open a Windi, look at it, and decide they will not be using it. At $12.74 that is a survivable outcome. The listing does not publish a count, which is annoying on a single-use product, so treat this as a trial box rather than a value calculation.
Verified: Frida Baby Windi Gas Passer, baby gas relief, described in the listing title as made in the USA. The title does not publish a count, so no cost per use is computed. Live at $12.74 on Amazon, verified via the Creators API on September 5, 2026.
Start here rather than with the big box. The smaller Windi listing is $12.74. The title does not state how many are in it, so we publish no count and compute no cost per use, but the price is roughly half the 20 count box and the risk of finding out you dislike the product is halved with it.
If it does suit you, move to the 20 count box, where the count is published and the arithmetic works out at about $1.25 each. If it does not, you are $12.74 down instead of $24.92.
Who should buy it
Buy this box first if you have never used a Windi. It is the cheapest way to find out whether you will actually use it, which is the only question that matters at this stage.
What we don't like
No count in the listing title, which on a single-use consumable makes it impossible to compare against the 20 count box on value. You are buying a trial rather than a known quantity.

What we like
- $12.74, roughly half the outlay of the large box
- The low-risk way to discover whether you will use the product
- Same drug-free single-use design as the larger box
Worth noting
- Count not published, so no cost per use can be computed
- Likely to run out quickly if the Windi does suit your baby
- Same limitation as the whole range: gas only
Frida Baby Fart Freeing Essentials
Frida Baby
The Windi paired with a gassy belly rub, count not published.
Our verdict: Two approaches to the same complaint in one purchase, at a price between the small and large Windi boxes. The belly rub adds a product to a massage routine most parents already do with clean hands, so the bundle mostly saves you a decision rather than money.
Verified: Frida Baby Fart Freeing Essentials, a bundle including the Windi and a gassy belly rub per the listing title. The Windi count in the bundle is not published, so no cost per use is computed. Live at $19.99 on Amazon, verified via the Creators API on September 5, 2026.
What is in it. Fart Freeing Essentials pairs the Windi with a gassy belly rub at $19.99. Massage is a normal part of dealing with a gassy baby, and a topical rub gives it a product form. Neither item is a drug and neither carries a Drug Facts panel.
Where the bundle makes sense is as a starting point for a parent who has tried neither and wants both in one order. Where it does not is for a household that already knows the Windi works, in which case the big box is the better buy.
Who should buy it
Buy the bundle if you want the massage product alongside the tool and would rather make one decision than two. It suits a parent still working out what will help.
What we don't like
No published Windi count, so $19.99 buys an unknown quantity of the thing you actually came for, and the rub adds cost to a routine that requires no product at all.
- Type
- Device plus topical rub, drug free
- Active ingredient
- None; not a drug or a supplement
- Count
- Not published in the listing title
- Form
- Windi vent tubes plus a gassy belly rub
- Label ages

- Bundle carton
What we like
- Two gas approaches in a single order
- Drug free and supplement free, with nothing absorbed
- Priced between the small and large Windi boxes
Worth noting
- Windi count not published, so no value comparison is possible
- The belly rub duplicates something parents already do for free
- No help at all with constipation
BioGaia Baby Probiotic Drops
BioGaia
The best-known baby probiotic drop, a dietary supplement rather than a medicine.
Our verdict: The other thing parents buy in the same moment, and the honest benchmark for the Windi. BioGaia is a dietary supplement, so nothing about it is approved to treat colic, gas or anything else, and the colic and gas wording in its Amazon title is the maker's. The Windi does one specific mechanical thing; a supplement promises nothing that a label can back.
Verified: BioGaia Baby Probiotic Drops, a dietary supplement carrying a Supplement Facts panel, marketed as safe for newborns per the listing title. Bottle volume and servings are not published in the title, so no cost per serving is computed. Live at $17.58 on Amazon, verified via the Creators API on September 5, 2026.
A different category entirely. BioGaia Baby Probiotic Drops carry a Supplement Facts panel rather than a Drug Facts panel, at $17.58. That is the most important thing to know about them and about every product in the category.
Parents commonly try drops on a pediatrician's suggestion, often alongside rather than instead of the Windi, which is a reasonable way to use them. Neither listing on this shelf publishes a serving count, so cost per day cannot be worked out for either. The full comparison is best baby probiotic drops.
Who should buy it
Buy BioGaia if a pediatrician has suggested a probiotic and you want the most recognised brand in the category. It is a supplement decision, not a treatment decision.
What we don't like
A supplement cannot promise an outcome, the listing publishes neither volume nor servings so $17.58 cannot be evaluated per use, and the condition words in the title set expectations the category cannot meet.
- Type
- Dietary supplement, Supplement Facts panel
- Active ingredient
- See the Supplement Facts panel; not a drug active
- Servings per bottle
- Not published in the listing title
- Form
- Liquid drops with a dropper
- Label ages
- Marketed for newborns and up; follow the panel
- Cost per serving
- Not computed, servings not published
- Packaging
- Bottle with dropper
What we like
- The most recognised baby probiotic drop among parents and clinicians
- Simple dropper format suitable for a newborn
- Nothing rectal, which some parents strongly prefer
Worth noting
- A dietary supplement, not approved to treat any condition
- Servings not published, so cost per serving cannot be computed
- Condition words in the listing title overpromise for the category
Mommy's Bliss Baby Probiotic Drops Everyday
Mommy's Bliss
The widely stocked alternative at $17.97, same category, same limits.
Our verdict: Effectively interchangeable with BioGaia on anything a label can support, at 39 cents more, and easier to find in a physical store. Its Amazon title stacks gas, constipation and colic onto a supplement, which is the boldest wording in this comparison and worth naming.
Verified: Mommy's Bliss Baby Probiotic Drops Everyday, a dietary supplement carrying a Supplement Facts panel, marketed for newborns and up per the listing title. Bottle volume and servings are not published, so no cost per serving is computed. Live at $17.97 on Amazon, verified via the Creators API on September 5, 2026.
Same shelf, bolder title. Mommy's Bliss Baby Probiotic Drops Everyday are a dietary supplement at $17.97, whose Amazon listing title includes the words gas, constipation and colic. Those are the maker's words in a marketing title. A supplement is not approved to treat any of the three.
If constipation is genuinely the problem, neither drop is the answer and neither is the Windi. That is the drug shelf, covered in baby constipation relief, and under age 2 it begins with a call to the pediatrician.
Who should buy it
Buy Mommy's Bliss if it is the drop your pediatrician named or the one your store stocks. As a supplement choice it is perfectly reasonable and effectively a coin flip against BioGaia.
What we don't like
The title stacks three condition words onto a supplement, no serving count is published, and it costs slightly more than the better known alternative with nothing verifiable to show for it.

What we like
- Widely stocked in physical stores
- From a house with a broad and familiar baby range
- Within 39 cents of the category leader
Worth noting
- Listing title stacks gas, constipation and colic onto a supplement
- Servings not published, so cost per serving cannot be computed
- Slightly more expensive with no verifiable advantage
What you'll need
The six things that go in the same cart as a suppository: the pharmacy-standard glycerin, a daily stool softener, an enema for the nights nothing else works, witch hazel wipes, sitz salts, and a barrier ointment. Prices are approximate at time of writing.

How we chose
The Windi is general merchandise rather than a labeled medicine, so we review it the way we review any device: what the listing states it is and is made for, how it is constructed, what it costs per use where a count is published, and what owners consistently report about using it. Every listing was verified live through the Amazon Creators API on September 5, 2026 and prices are hedged to that date. We do not claim any clinical effect for it, because the product does not claim one either, and we weigh owner testimony for the practical questions only: how the stopper behaves, how parents position a baby, and whether the box sizes are worth their prices.
Compliance for this page. The Windi is a device with no active ingredient and no Drug Facts panel, so nothing here presents it as treating a condition. The probiotic drops it is benchmarked against are dietary supplements: these statements have not been evaluated by the Food and Drug Administration, and these products are not intended to diagnose, treat, cure, or prevent any disease. Where an Amazon listing title carries condition words, those are the maker's own and we report them rather than adopt them. Anything to do with a baby's bowels or persistent distress is the pediatrician's decision, and every pediatric laxative label sends children under 2 to a doctor. Nothing on this page is medical advice.
Questions, answered
Does the Windi actually work?
Owners are consistently positive about it for its one specific job, releasing trapped gas, and consistently clear that it is not a cure for a generally unhappy baby. It is a mechanical device with no medicine in it, so what it does is limited and physical rather than pharmacological. The honest summary is that parents who buy it for gas tend to be satisfied and parents who buy it for constipation tend not to be, which is why this review spends so long on telling the two apart.
Does the Windi help with constipation?
No, and it does not claim to. The Windi is a vent tube for trapped gas. It contains no laxative and carries no Drug Facts panel, and it will not soften a hard stool or move an infrequent one. If your baby's stools are hard, pellet-like or noticeably less frequent than their own pattern, that is the constipation shelf, and for a child under 2 every pediatric laxative label tells you to ask a doctor before using anything.
How much does a Windi cost per use?
About $1.25 on the 20 count box, which was $24.92 on September 5, 2026 and is the only listing in the range that publishes a count. The smaller box at $12.74 and the Fart Freeing Essentials bundle at $19.99 do not publish counts, so no cost per use can honestly be computed for either. Since the Windi is single use with no reusable part, that per-use figure is the number worth planning around before you commit to the format.
Is the Windi safe for a newborn?
It is marketed for babies and infants and its design includes a stopper that limits how far it can be inserted, which is the feature owners cite most often. It is a device rather than a medicine, so nothing is absorbed and nothing interacts with anything else your baby is given. Read the packaging instructions before you need them, never force it, stop at any resistance, and if you have any doubt about whether it is appropriate for your baby, that is a question for your pediatrician.
Which Windi box should I buy?
Buy the smaller box at $12.74 first if you have never used one, because a fair number of parents open the packet and decide it is not for them. If it works for your baby, move to the 20 count at $24.92, about $1.25 per Windi, which is the only listing whose value can actually be assessed because it is the only one publishing a count. The bundle at $19.99 makes sense only if you specifically want the belly rub too.
Windi or probiotic drops?
They are not really competitors. The Windi is a device that does one physical thing for trapped gas. Probiotic drops are dietary supplements that are not approved to treat any condition, including gas and colic, and whose Amazon titles carry condition words the makers wrote. Plenty of families use both, usually on a pediatrician's suggestion. If you want one thing that addresses a specific, identifiable problem right now, that is the Windi.
Can you reuse a Windi?
No. Every unit is single use by design and there is no reusable component, which is the source of the ongoing cost and the main practical criticism of the product. At about $1.25 per use on the 20 count box, a phase of frequent evening gas gets expensive quickly, and that is worth knowing before you commit to the format rather than after the second box.
