Preemies are gassy. Immature digestive systems, air swallowed during careful bottle feeds, and reflux all add up to a baby who pulls their knees up, grunts, and fusses in a way that's genuinely hard to watch at 3am. The good news: most of what helps isn't a product at all. The important news: for a premature baby, you should clear any drops or remedies with your pediatrician before you use them.

Here's what actually helps with preemie gas, in the order worth trying it.

Technique first — it often helps more than any product

• Paced bottle feeding — horizontal bottle, frequent pauses — so your baby swallows less air to begin with.
• Burp partway through and after every feed, and keep your baby upright for 20–30 minutes afterward.
• Bicycle legs and gentle tummy massage when your baby is calm and awake help move trapped gas through.
• Supervised tummy time during awake periods builds the muscle tone that helps digestion along.

Simethicone gas drops (Mylicon)

Simethicone works mechanically — it breaks large gas bubbles into smaller ones — and isn't absorbed into the body, which is why it's generally considered low-risk. The honest caveat is that the evidence it actually reduces crying is weak. Many parents feel it helps; it's reasonable to try with your pediatrician's okay for your preemie.

The Windi: mechanical gas relief

The Frida Windi is a small, single-use soft tube that helps release trapped gas mechanically. Parents who use it tend to swear by it for the truly stuck moments. Use it exactly as directed and occasionally, not as a routine — and ask your pediatrician first, especially for a preemie.

A note on gripe water and probiotic drops

Gripe water is a herbal remedy that is not regulated by the FDA, and the evidence it works is thin. If you and your pediatrician decide to try it, choose an alcohol-free formula with no sodium bicarbonate, and read the ingredient list carefully. Probiotic drops are a separate and more cautious topic. In 2023 the FDA warned about probiotic products given to preterm babies in hospitals, after serious infections that included one death, and noted that no probiotic is FDA-approved as a treatment for babies of any age. That warning was about hospitalized preterm babies, but it's a good reason to check with your pediatrician before giving any probiotic to a preemie at home.

Why preemies seem gassier than other babies

Some of it is real and some of it is timing. The real part is that a preterm gut is genuinely less mature — motility is still developing, and coordinating a suck-swallow-breathe pattern takes practice, which means more air goes down with each feed than it would for a term baby.

The timing part is the one nobody explains. Normal infant crying follows a curve: it climbs for the first weeks, peaks, then settles. For a baby born early, that curve tracks corrected age, not the date on the birth certificate. So a baby born at 30 weeks may hit their fussiest stretch at around four months old on the calendar — long after friends with term babies have come out the other side, and long after you have started assuming something must be wrong.

Knowing that does not stop the crying. It does stop you concluding that the crying means you have missed something, which is worth a surprising amount at 3am.

Is it gas, reflux, or just the evening?

These get treated as one thing and they are not, which matters because the responses differ. Gas tends to come with pulled-up knees, straining, and relief after passing it. Reflux tends to cluster around and after feeds, with arching, and sometimes with feed refusal because the feeding itself has started to hurt. The ordinary evening fussy stretch is not tied to feeds at all — it shows up at roughly the same time each day and resolves on its own timeline.

You do not have to diagnose which one it is. But writing down when the crying starts relative to feeds, for three or four days, turns a vague "he's so fussy" into something your pediatrician can act on in a ten-minute appointment.

Be careful what you buy at this stage

Infant colic is a large market aimed squarely at exhausted people, and very little of it is tested on premature babies specifically. Herbal teas and tinctures, anything marketed as a gut cleanse, and any drop with an ingredient list you cannot pronounce all belong in the same category: ask first. Sodium bicarbonate and alcohol in particular have no business going into a preemie.

Probiotics deserve a second mention because it matters: the FDA's 2023 warning was specifically about preterm babies in hospitals, but no probiotic is FDA-approved as a treatment for babies of any age. Ask your pediatrician before starting one, however good the review section looks.

What helped us most, and it was free

Slowing the feed down. We were using a nipple one flow rate too fast without realising, because it had been fine in the NICU when he was being fed smaller volumes. Dropping back a level meant longer feeds and a much calmer hour afterwards. If you change one thing before buying anything, change the flow rate — and tell your team you have.

The second thing was accepting that some evenings we were not going to fix it, and taking it in shifts so that whoever was holding him was not also running on empty. That is not gas advice. It is the advice I would actually give another preemie parent.

When gas isn't just gas — call your pediatrician

Fussiness paired with poor weight gain, forceful or projectile vomiting, blood or mucus in the stool, arching and inconsolable pain, or feeding refusal is not ordinary gas. These can signal reflux that needs treatment, a cow's-milk protein allergy, or something more serious — call your pediatrician rather than reaching for another remedy.
