Introduction
Watching your baby cry for hours can feel overwhelming and exhausting. You have checked the diaper, offered the breast, and tried every rocking motion you know, yet the fussiness continues. This intense, rhythmic crying is often labeled as colic, and it affects about one in five families. It is a season of parenting that tests your patience and your heart, but please know that you are doing an amazing job.
At Milky Mama, we know that when your baby is uncomfortable, you will do anything to find them relief. Many parents begin to wonder if something in their own diet is causing the tummy trouble. While colic is a complex issue with many potential causes, looking at what you eat is a practical place to start. If you want more context on the topic, our guide to breastfeeding and colic is a helpful companion read.
In this article, we will explore the common dietary triggers that may contribute to infant fussiness. We will also discuss how to safely navigate an elimination diet and how to support your own nutrition during this time. Our goal is to help you understand what foods to avoid breastfeeding colic so you and your baby can get some much-needed rest.
Understanding Colic and Your Milk
Colic is generally defined by the "rule of three." This means a baby cries for more than three hours a day, for more than three days a week, for three weeks or more. These episodes usually peak around six weeks of age and often resolve on their own by four months. It is important to remember that colic happens in otherwise healthy, well-fed babies.
You might wonder how your lunch could possibly affect your baby’s evening crying spell. When you eat, nutrients and proteins from your food are broken down and enter your bloodstream. From there, some of these molecules pass into your breast milk. For most babies, this is perfectly fine and actually helps their immune system.
However, some infants have a more sensitive digestive system. Their gut is still maturing, and certain proteins can cause inflammation or gas. When this happens, the baby may become fussy, arch their back, or pull their legs up in pain. By identifying and removing these triggers, many parents see a noticeable change in their baby's comfort level.
The Most Common Trigger: Dairy Products
When looking at what foods to avoid breastfeeding colic, dairy is almost always at the top of the list. Cow’s milk protein is the most common allergen for infants. It is important to distinguish between a lactose intolerance and a cow’s milk protein allergy (CMPA).
True lactose intolerance is actually very rare in infants. Breast milk naturally contains high levels of lactose, regardless of what the mother eats. The more common issue is a sensitivity or allergy to the specific proteins found in cow's milk, such as whey and casein. When a nursing mother consumes milk, cheese, or yogurt, these proteins can pass into her milk and irritate the baby's intestinal lining.
If your baby has a dairy sensitivity, you might notice:
- Excessive gas and bloating
- Skin rashes or eczema
- Green, mucousy stools
- Extreme fussiness shortly after feeding
If you decide to cut out dairy, be patient. It can take up to two weeks for cow's milk protein to completely leave your system and your baby's system. You may not see an immediate change overnight, but staying consistent is key.
Caffeine and Baby’s Irritability
Many of us rely on a morning cup of coffee to navigate the sleepless nights of early parenthood. However, caffeine is a stimulant that passes into breast milk. While most babies can handle a moderate amount, some are very sensitive to it.
A baby's body cannot break down caffeine as quickly as an adult's body. This can lead to the caffeine building up in their system over time. If you are consuming high amounts of coffee, soda, or energy drinks, your baby might become jittery and restless. This irritability can often mimic or worsen colic symptoms.
Don’t forget about hidden sources of caffeine. Chocolate, certain teas, and even some over-the-counter headache medications contain caffeine. If your baby seems "wired" or has trouble settling down even when they are clearly tired, try reducing your caffeine intake for a few days to see if their temperament improves.
High-Gas Vegetables and Legumes
You may have heard that "gassy" vegetables like broccoli and cabbage will make your baby gassy. This is a bit of a controversial topic in the lactation world. The fiber in these vegetables, which causes gas in adults, does not pass into breast milk. However, the complex sugars and certain proteins do.
For some babies, these components can lead to extra wind and discomfort. Common culprits include:
- Broccoli and cauliflower
- Cabbage and Brussels sprouts
- Onions and garlic
- Beans and lentils
If you notice your baby is particularly fussy after you eat a large bowl of bean chili or a plate of roasted broccoli, it might be worth a temporary break from those foods. Every baby is different, so while one baby might be fine with garlic, another might find it very upsetting.
Common Food Allergens Beyond Dairy
If cutting out dairy doesn't seem to help, there are other common allergens that may be the culprit. About 30% of babies who are sensitive to dairy are also sensitive to soy. This is because the proteins in soy are structurally similar to the proteins in cow's milk.
Other foods to watch include:
- Wheat and Gluten: Some babies react to the gluten protein found in wheat, barley, and rye.
- Eggs: Egg whites, in particular, are a common allergen that can cause digestive upset in infants.
- Nuts: Peanuts and tree nuts can cause sensitivities, though this is often linked more to skin issues or respiratory symptoms.
- Corn: Corn syrup and corn solids are in many processed foods and can be a hidden trigger for fussiness.
Identifying these can be tricky because they are hidden in so many packaged items. Reading labels becomes very important when you are trying to determine what foods to avoid breastfeeding colic.
Spicy and Acidic Foods
Some babies are sensitive to the flavors and chemicals in spicy foods. Capsaicin, the compound that makes peppers hot, can end up in your milk. While some babies don't mind the "extra kick," others may experience a mild burning sensation or digestive upset.
Acidic foods can also play a role. Citrus fruits like lemons, limes, oranges, and grapefruits, as well as tomatoes, can sometimes cause diaper rash or reflux symptoms in sensitive babies. If your baby struggles with "spitting up" frequently along with their crying spells, reducing acidic foods might provide some relief.
Key Takeaway: There is no single "colic diet" that works for every baby. The best approach is to stay observant and look for patterns between what you eat and how your baby behaves.
How to Start an Elimination Diet
If you suspect your diet is impacting your baby, an elimination diet is the most effective way to find answers. This involves removing potential trigger foods for a set period and then slowly reintroducing them.
- Keep a Food Journal: Write down everything you eat and drink. Also, track your baby’s crying episodes, gas, and bowel movements. You may start to see a pattern after just a few days.
- Start Small: Don't cut out everything at once. Start with the most likely culprit, which is usually dairy.
- Give it Time: As mentioned, it can take two weeks for proteins to clear your system. Don't give up after three days if you don't see a change.
- Reintroduce Slowly: If your baby’s symptoms improve, try eating a small amount of the food again. If the crying returns, you have found your trigger.
It is vital to stay nourished during this process. Many moms worry that they won't have enough to eat if they cut out dairy or wheat. Focus on whole foods like lean meats, rice, potatoes, and non-cruciferous vegetables.
Supporting Your Supply While Changing Your Diet
When you are cutting out entire food groups, it is easy to accidentally drop your calorie intake. This can sometimes lead to a dip in milk supply. It is important to replace those calories with nutrient-dense alternatives.
At Milky Mama, we offer several ways to support your lactation journey while you navigate these changes. Our herbal supplements, like Lady Leche™ or Pump Hero™, are designed to support milk production without relying on common food triggers. If you are looking for a treat that is dairy-free, our Emergency Lactation Brownies are a favorite for many moms.
Hydration is also essential. If you are cutting out soda or sugary coffee, Pumpin' Punch™ or Lactation Drink Mixes can help you stay hydrated and support your supply with a refreshing, baby-friendly flavor. You can also browse our full Lactation Supplements collection for more options.
Non-Dietary Ways to Help a Colicky Baby
While we are focusing on what foods to avoid breastfeeding colic, it is helpful to remember that diet is only one piece of the puzzle. Sometimes, babies cry because their nervous system is simply overloaded.
Try these comforting techniques alongside your dietary changes:
- The "Colic Carry": Hold your baby face down along your forearm, with their head in your hand and their legs straddling your elbow. The gentle pressure on their tummy can help move gas.
- White Noise: The womb was a very loud place. A loud white noise machine or a vacuum cleaner sound can be very soothing to a distressed infant.
- Warm Baths: A gentle warm bath can help relax your baby's muscles and distract them from their discomfort.
- Skin-to-Skin: Never underestimate the power of your touch and smell. Stripping the baby down to a diaper and laying them on your bare chest can regulate their heart rate and breathing.
If you want more support beyond the basics, our Certified Lactation Consultant Breastfeeding Help page is a good place to start, and our Breastfeeding 101 course collection can also be a helpful next step.
When to Seek Professional Help
It is always a good idea to keep your pediatrician in the loop. While colic is common, you want to rule out other medical issues like an ear infection, a urinary tract infection, or severe reflux.
You should call the doctor if your baby:
- Has a fever
- Is not gaining weight
- Has projectile vomiting
- Has blood in their stool
- Cries in a way that sounds like an emergency or true pain
A Certified Lactation Consultant (IBCLC) can also be an incredible resource. They can check your baby's latch to ensure they aren't swallowing too much air during feedings, which can lead to gas that looks like colic. If latch or transfer feels off, our guide on how to get a good breastfeeding latch can help, and our article on understanding low milk supply is a useful follow-up if you are also worried about intake.
Summary of Action Steps
If you are ready to tackle colic through your diet, follow these simple steps:
- Audit your dairy intake: Switch to plant-based milks (like oat or almond) for two weeks.
- Watch the caffeine: Limit yourself to one cup of coffee early in the day.
- Keep a log: Note what you eat and when the "witching hour" begins for your baby.
- Focus on hydration: Drink plenty of water or lactation-supportive drinks.
- Be patient with yourself: You are doing the best you can for your baby.

FAQ
How long does it take for a change in my diet to help my baby's colic?
For most foods, you may see an improvement within 3 to 7 days. However, cow’s milk protein can stay in your system for up to two weeks, so it is important to remain dairy-free for at least 14 days before deciding if it worked. If the food was a trigger, the baby’s fussiness and gas should gradually decrease during this time.
Can I still have chocolate if I am avoiding caffeine for my colicky baby?
Chocolate contains small amounts of both caffeine and theobromine, which are both stimulants. While a small piece is usually fine for most babies, a baby who is extremely sensitive to stimulants may react to it. If you suspect caffeine is a trigger, it is best to limit chocolate until your baby's symptoms improve.
Does spicy food always cause colic in breastfed babies?
No, spicy food does not cause colic in every baby. Many cultures around the world consume very spicy diets while breastfeeding without any issues. However, some babies may be sensitive to the flavors or the capsaicin in the milk, so it is worth observing your baby's reaction after you eat a spicy meal.
Is it okay to use gas drops while I am trying to figure out my diet?
Yes, many parents use simethicone gas drops to help break up large gas bubbles in the baby's tummy. While these drops don't "cure" colic, they can provide temporary relief from the pressure of gas. Always consult your pediatrician before starting any new supplements or medications for your infant.
