A Look at What the Evidence Says (and What You Can Stop Feeling Guilty About)
If you’ve ever had a gassy or fussy baby while breastfeeding, chances are someone has said: “It’s probably something you ate.” Maybe it was dairy. Or broccoli. Or spicy food. Or garlic. Or chocolate. Or… anything at all.
As a postpartum doula, I hear this concern from new moms all the time. The truth is: this idea has been circulating for decades—but what does the research actually say?
Let’s explore the facts, the myths, and the very real feelings that come with trying to feed your baby and yourself at the same time.
💨 First, Let’s Talk About Baby Gas
Gas is normal for babies. Their digestive systems are immature, and it takes time for them to figure out how to manage swallowing, feeding, and pooping efficiently. Common causes of gas include:
Swallowing air while feeding or crying
A tight latch or fast milk letdown
Normal digestion and gut bacteria development
Sensitivity or intolerance (which is rare, but possible)
So while your baby might be gassy after you eat certain foods, it’s not automatically your fault—and in many cases, it’s not related to your diet at all.
🥦 Is It What I Ate? The Research on Diet and Breastmilk
Here’s what we know from evidence-based sources:
Most foods in your diet do not cause gas in your baby. According to My baby is gassy. Is this caused by something in my diet? - KellyMom.com, gas-producing foods like beans, broccoli, and cabbage don't necessarily cause gas in breastfed babies. Why? Because the gas-causing compounds in those foods stay in your digestive tract, not your milk.
True food sensitivities are uncommon. Around 2–3% of exclusively breastfed babies may have a cow’s milk protein allergy (CMPA), which can cause discomfort, rash, or blood in the stool. But it’s not just mild gassiness. If you suspect this, consult with your pediatrician before eliminating dairy.
Breastmilk is remarkably consistent. A 2019 study in Nutrients Maternal Lifestyle Factors Affecting Breast Milk Composition and Infant Health: A Systematic Review - PMC found that while the composition of breastmilk can shift slightly depending on maternal diet (like fatty acids), it remains nutritionally complete and balanced for your baby—even if your own diet isn’t perfect.
Restrictive diets are not usually needed—and may do more harm than good. Going dairy-free, soy-free, or gluten-free without medical guidance can increase stress, reduce your caloric intake, and make postpartum life even harder. Always talk to a provider before eliminating major food groups.
🔍 When to Investigate Further
In most cases, baby gassiness is temporary and normal. But here are signs that it might be worth talking to your pediatrician:
Blood or mucus in baby’s stool
Severe eczema or rash
Poor weight gain
Excessive vomiting or diarrhea
Signs of pain that don’t improve with normal soothing techniques
If these show up, your provider may recommend an elimination diet or refer you to a pediatric allergist or lactation consultant for support.
🤱 Bottom Line: Trust Your Gut (Literally)
There’s no need to preemptively eliminate foods from your diet unless there’s a clear medical reason. Breastfeeding is hard enough without second-guessing every meal or snack.
Instead:
Focus on eating enough calories and staying hydrated
Watch your baby, not the clock or food lists
Get support from a lactation consultant, pediatrician, or doula (I’m always here!) if you’re unsure
