Introduction
Watching your baby cry for hours can feel heartbreaking and exhausting. You have checked their diaper, offered a feeding, and tried every rocking motion you know. When the crying continues without a clear cause, many parents begin to wonder if colic is the culprit. Colic can be a mystery, but many families find that small changes in the nursing parent's diet make a significant difference.
At Milky Mama, we know that you want to do everything possible to comfort your little one. We provide support to breastfeeding families through every high and low of the journey, including our breastfeeding help and virtual consultation support. In this post, we will explore the common dietary triggers that may contribute to colic symptoms. We will also discuss how to identify these foods and what you can eat instead to keep yourself nourished. Making informed choices about your nutrition may help both you and your baby find much-needed relief.
What Exactly Is Colic?
Colic is generally defined by the "rule of three." This means an otherwise healthy baby cries for more than three hours a day. This happens at least three days a week for three weeks or more. These crying episodes often peak in the late afternoon or evening. During these times, your baby might seem impossible to soothe.
You may notice your baby pulling their legs up toward their tummy. They might clench their fists or have a very red face while crying. It is important to remember that colic is a phase, not a permanent condition. Most babies grow out of it by the time they are three or four months old. While it is temporary, it is still very stressful for parents who are already short on sleep.
Colic is not a reflection of your parenting skills. It is not anyone's fault. While the exact cause is not fully understood, many experts believe it relates to a developing digestive system. Some babies are simply more sensitive to the proteins or compounds that pass from your diet into your breast milk.
How Your Diet Impacts Your Breast Milk
Everything you eat and drink is processed by your body. Small amounts of the proteins and chemicals from your food can enter your bloodstream and then your milk. For most babies, this is never an issue. However, some infants have more sensitive guts. Their digestive systems are still learning how to process these foreign proteins.
When a baby has a sensitivity, it can lead to gas, bloating, and intestinal discomfort. This physical pain often manifests as the intense crying we associate with colic. By adjusting what you eat, you can potentially reduce the irritants in your milk. This is often the first step in helping a colicky baby feel more comfortable.
Key Takeaway: Your breast milk is perfectly made for your baby, but certain proteins from your diet can sometimes cause temporary digestive upset in sensitive newborns.
The Most Common Trigger: Dairy Products
Cow’s milk protein is the most frequent dietary trigger for colic in breastfed infants. It is important to distinguish between a milk protein allergy and lactose intolerance. True lactose intolerance is very rare in infants. Most babies have plenty of lactase, which is the enzyme needed to break down the natural sugar in breast milk.
The issue is usually the proteins found in dairy, such as whey and casein. These proteins can pass into your milk and irritate your baby’s intestinal lining. If your baby has a dairy sensitivity, you might notice more than just crying. They may also have skin rashes, congestion, or green, mucus-like stools.
How to Manage a Dairy Sensitivity
If you suspect dairy is the problem, you may want to try removing it from your diet for two weeks. This includes milk, cheese, yogurt, butter, and ice cream. It also includes "hidden" dairy in processed foods, often labeled as whey, casein, or milk solids.
It takes time for dairy proteins to leave your system and your baby's system. You might not see a change in the first 48 hours. Many parents see a significant improvement after about ten days of being dairy-free. If your baby’s colic improves, you have found your primary trigger.
Caffeine and Infant Irritability
Many new parents rely on coffee to get through the day. However, caffeine is a stimulant that passes into breast milk. Most babies can handle a small amount of caffeine. However, some are very sensitive to it. A baby’s body takes a long time to process and clear caffeine from their system.
If you consume high amounts of coffee, soda, or energy drinks, it can lead to restlessness. Your baby may become overtired because they cannot fall asleep easily. An overtired baby is often a fussy, colicky baby. If your little one seems wired or jittery, try reducing your caffeine intake.
Safe Alternatives to High Caffeine
- Switch to decaf coffee or herbal teas.
- Try sparkling water instead of caffeinated sodas.
- Monitor your chocolate intake, as it contains small amounts of caffeine.
Cruciferous Vegetables and Gas
Vegetables like broccoli, cauliflower, cabbage, and Brussels sprouts are incredibly healthy. They are packed with fiber and vitamins. However, they are also known as "gas-producing" foods. They contain a complex sugar called raffinose. Humans lack the enzyme to break down raffinose in the small intestine.
When this sugar reaches the large intestine, bacteria break it down, producing gas as a byproduct. While the gas itself does not pass into your milk, some of the gas-forming compounds can. If your baby seems particularly gassy after you eat a large bowl of steamed broccoli, it might be worth limiting these for a short time.
Gentle Vegetable Options
If you are avoiding cruciferous greens, focus on these instead:
- Carrots
- Zucchini
- Spinach
- Sweet potatoes
- Squash
Spicy Foods and Flavor Changes
Strong flavors like garlic, onions, and hot peppers can change the taste and smell of your milk. Many babies actually enjoy these variations. In some cultures, spicy food is a daily staple, and babies do just fine. However, some infants may find these flavors irritating.
Spicy ingredients can sometimes cause a mild form of acid reflux in babies. This is when the stomach contents move back up into the esophagus, causing a burning sensation. If your baby arches their back and cries during or after a feeding, they might be experiencing reflux.
What to Do Next
- Keep a simple food log for three days.
- Note the times your baby is most fussy.
- Look for patterns between spicy meals and crying spells.
High-Allergen Foods to Watch
Beyond dairy, other common allergens can contribute to infant fussiness. If your baby has a family history of allergies, they might be more reactive. These foods do not cause colic in every baby, but they are common culprits in sensitive cases.
- Soy: Many babies who are sensitive to dairy are also sensitive to soy.
- Wheat: Gluten can be difficult for some developing digestive tracts to handle.
- Eggs: The proteins in egg whites are a common allergen.
- Nuts: Peanuts and tree nuts can occasionally cause reactions.
If you decide to remove these, do so one at a time. This makes it easier to tell exactly which food was causing the issue. Our Lady Leche™ herbal supplement is a popular choice for many moms during this time. It is formulated with herbs like moringa and nettle to support your milk supply while being gentle on the system.
The Role of Acidic Foods
Citrus fruits and tomatoes are highly acidic. For some nursing parents, eating a lot of these can lead to diaper rashes or digestive upset in their babies. The acid can irritate the baby’s gut or make reflux symptoms worse.
If you notice your baby gets a red, angry-looking rash around their bottom after you eat citrus, try cutting back. You can get your Vitamin C from other sources like bell peppers or strawberries, which are often better tolerated.
How to Start an Elimination Diet
An elimination diet sounds intimidating, but it is a temporary tool to find answers. You do not need to eat a bland diet forever. The goal is to find the specific food that is bothering your baby so you can return to a varied diet as soon as possible.
Step 1: Identify the Suspects
Start with the most likely culprits. Dairy is almost always the best place to begin. If you suspect multiple foods, you can remove the "Top 8" allergens (dairy, soy, wheat, eggs, peanuts, tree nuts, fish, and shellfish). However, this is very restrictive and can be hard to maintain.
Step 2: The Two-Week Wait
Remove the chosen food entirely for 14 days. Read labels carefully. You would be surprised how many "non-dairy" creamers actually contain milk derivatives. Stick to whole, unprocessed foods as much as possible during this window.
Step 3: Observe and Record
Watch your baby’s behavior closely. Is the crying less intense? Is the gas passing more easily? Are they sleeping better? Record these changes in your food log.
Step 4: The Challenge
If the baby is doing better, try eating a small amount of the eliminated food. If the colic symptoms return within 24 to 48 hours, you have confirmed the trigger. If no reaction occurs, that food is likely safe, and you can move on to the next suspect.
Nourishing Yourself While Avoiding Triggers
It is easy to focus so much on the baby that you forget to eat properly. Restricting your diet can lead to calorie deficits and nutrient gaps. This can impact your energy levels and your milk supply.
At Milky Mama, we believe that your well-being matters just as much as your baby's. You need to stay hydrated and nourished to keep up with the demands of a colicky infant. Our Pumpin' Punch™ drink mix is a great way to stay hydrated while supporting your lactation. It provides a boost of hydration without the caffeine that might irritate a sensitive baby.
Safe Foods to Enjoy
While you are navigating an elimination diet, focus on these nutrient-dense options:
- Oats: A wonderful grain that supports supply and is usually very gentle.
- Lean Proteins: Chicken, turkey, and beef (if dairy-free).
- Healthy Fats: Avocado and olive oil provide essential fatty acids.
- Quinoa and Rice: Great gluten-free alternatives to wheat.
Our Emergency Lactation Brownies are another favorite for busy parents. They are made with oats and flaxseed. These ingredients are generally well-tolerated by babies and provide a much-needed treat for a tired mom.
When to Seek Professional Help
While dietary changes help many families, colic can sometimes mask other issues. If your baby is not gaining weight, has a fever, or seems lethargic, contact your pediatrician immediately.
It is also helpful to work with an International Board Certified Lactation Consultant (IBCLC). They can check your baby’s latch. Sometimes, a poor latch causes the baby to swallow too much air, which leads to gas and "colic-like" symptoms. We offer virtual consultations to help you navigate these challenges from the comfort of your home.
Key Takeaway: If dietary changes do not seem to help after a few weeks, consult a professional to rule out other issues like tongue ties or oversupply.
Practical Comfort Measures for Colic
While you wait for dietary changes to take effect, you need ways to soothe your baby in the moment. These techniques do not fix the dietary issue, but they can help calm the nervous system.
- The "Colic Carry": Lay your baby face-down along your forearm, with their head in your hand and legs straddling your elbow. The gentle pressure on their tummy can help move gas.
- White Noise: The sound of a vacuum, fan, or white noise machine mimics the sounds of the womb. This can be very soothing for an overstimulated baby.
- Warm Baths: A warm bath can help relax tense muscles.
- Skin-to-Skin: Holding your baby against your bare chest helps regulate their heart rate and temperature. It also releases oxytocin, which helps you both feel calmer.
Staying Positive Through the Crying
Caring for a colicky baby is one of the hardest parts of early parenthood. The constant crying can trigger a "fight or flight" response in your brain. It is okay to feel frustrated. It is okay to put the baby in a safe place, like their crib, and walk into another room for five minutes to breathe.
Remember our motto: You are doing an amazing job. This phase will pass. Your baby’s digestive system will mature, and the evening hours will eventually become peaceful again.
Summary of Foods to Avoid
If you are looking for a quick reference, here is a summary of foods that may contribute to colic:
- Dairy Products: The most common irritant; includes milk, cheese, and yogurt.
- Caffeine: Can cause restlessness and prevent deep sleep.
- Cruciferous Veggies: Broccoli and cabbage can increase gas compounds.
- Allergens: Soy, wheat, and eggs are frequent triggers for sensitive babies.
- Spicy/Acidic Foods: Can contribute to reflux and flavor aversions.
Every baby is different. You might find that you can eat spicy curry but need to avoid cheese entirely. Trust your instincts and your observations of your baby.
Conclusion
Navigating colic is a journey of patience and observation. While the exact cause of those long crying spells remains a bit of a mystery, many breastfeeding families find relief through dietary adjustments. By identifying triggers like dairy or caffeine and focusing on gentle, nourishing foods, you can support your baby's developing digestive system.
- Start with a food log to track patterns.
- Try a two-week dairy-free trial as your first step.
- Focus on hydration and nutrient-dense meals to maintain your energy.

FAQ
How long does it take for food to leave breast milk?
Most food proteins and compounds peak in your milk about two to six hours after you eat. However, some proteins, like those from cow's milk, can linger in your system for several days. If you are doing an elimination diet, it usually takes about two weeks to see a full change in your baby's symptoms.
Is it safe to stop eating multiple food groups while breastfeeding?
While you can temporarily remove certain foods, you must ensure you are still getting enough calories and nutrients. If you cut out dairy, for example, make sure you are getting calcium from leafy greens, sardines, or fortified alternatives. If you plan on a very restrictive diet, it is best to consult with a dietitian or your healthcare provider.
Can herbal supplements help with my baby's colic?
Some herbs are traditionally used to support digestion and reduce gas. However, you should always check with a lactation professional before starting a new herbal regimen. Our products, like Lady Leche™ or another Milky Mama supplement, are designed to support your journey without common irritants.
Will my baby always be sensitive to these foods?
In most cases, no. Colic and food sensitivities in newborns are usually due to an immature digestive tract. As your baby grows and their gut microbiome develops, they will likely be able to handle these proteins. Many parents find they can slowly reintroduce "trigger" foods once the baby is six months or older.
