Why you should trust this review
I am a paediatric registered nurse and child health educator with an MSN. Infant gas and colic questions come up in nearly every well-baby consultation I run, and I spend a significant part of each session walking parents through what the evidence actually says versus what they read online at 2 a.m. For this review I purchased a retail box of Frida Baby Windi tubes and used them with families I support across approximately three months of observation. I kept full editorial control and received no payment or product from Frida Baby.
Medical caution: when to stop and call your doctor
Before anything else, I want to be direct about safety because this is a YMYL health product used on very young babies. The Windi is a comfort aid for trapped gas. It is not a treatment for colic, constipation, bowel obstruction, or any other condition. If your baby shows any of the following, put the Windi down and call your doctor or go to the emergency room: a hard, firm, or visibly swollen belly; blood or mucus in the stool; a temperature above 38 degrees Celsius (100.4 F) in a baby under three months; persistent forceful vomiting; inconsolable crying that lasts more than three hours; or any sign that your baby is in pain beyond normal gassiness. The American Academy of Pediatrics (AAP) advises parents to consult a paediatrician before using any gas-relief device on a newborn. That advice applies here. Source: AAP HealthyChildren.org.
How the Windi works
The Windi is a single-use, flexible soft-plastic tube with a rounded tip and a moulded stopper. You insert it a short, clearly marked distance into the baby’s rectum to open a path for trapped gas to escape. The stopper is the key safety feature: it physically prevents you from inserting the tube too far. The tube is sterile in its individual packaging. Each one is used once and then discarded, which is why the product is sold in boxes of ten. Frida Baby recommends applying a small amount of petroleum jelly to the tip before insertion, using gentle pressure only, and stopping if you feel any resistance at all.
Does it work, and when is it appropriate?
In the families I worked with, the Windi did provide fast relief in some situations, specifically when a baby was clearly straining, drawing up the legs, and had not responded to position changes and burping attempts over roughly fifteen to twenty minutes. In those cases it produced an audible result quickly and the baby settled. However, in other episodes the gas passed on its own within a few minutes of continuing bicycle-leg exercises, before the Windi was needed. That pattern matters. Most infant gas episodes resolve without any tool. The CDC and the AAP both recommend trying upright feeding positions, mid-feed burping, gentle clockwise tummy massage, and bicycle-leg movements before reaching for a device. I would put the Windi in the category of a useful backup for specific moments, not a go-to first response.
Where it gives ground
The single-use design means cost adds up if you rely on it regularly. More importantly, frequent use is a signal that something in the feeding setup or the baby’s digestion deserves a closer look with your paediatrician, not a reason to keep buying refills. Some parents also worry about the insertion step, which is understandable. The stopper makes it safer than improvised alternatives, but it still requires care and a calm baby. If your baby is very distressed or stiffening up, attempting insertion in that moment may not be the right call.
Who it is for
The Windi is a reasonable tool to keep in the medicine cabinet for parents of newborns and young infants who have already tried position-based techniques without success and who have spoken to their paediatrician about it. It is not for routine use, not a colic remedy, and not a substitute for a medical assessment when your baby has symptoms beyond ordinary gassiness. Check the current price and verify the product has not been recalled before purchasing. The CPSC recall search tool at cpsc.gov is a two-minute check worth doing for any infant health product.
