Baby Formula Intolerance: Signs, Symptoms & What to Do

How to Recognize Symptoms of Baby Not Tolerating Formula: A Practical Guide

New parents must recognize the signs of a baby not tolerating formula to know how to help. Understanding how to manage formula intolerance or allergy is essential to ensure your baby receives the necessary nutrients and stays comfortable. Your pediatrician can help you identify the causes and recommend the best solution for your baby.

What is Formula Intolerance, and What Causes It?

Formula intolerance occurs when the baby's digestive system cannot properly break down an ingredient in the formula they've ingested, causing one or more negative symptoms. It's not life-threatening, but the irritation within their digestive systems can cause slow weight gain and growth and the more acute symptoms of dehydration.

Common ingredients in baby formula, such as cow's milk, soy protein, and lactose, can be the culprits. Dairy products all contain lactose, a disaccharide. A disaccharide contains two sugars. In this case, lactose is made up of glucose and galactose.

Common Signs Your Baby May Not Be Tolerating Formula

Parents should be aware that gas, diarrhea or constipation, excessive crying, spitting up, and fussiness are typical occurrences after a formula feeding. These symptoms of formula intolerance usually resolve themselves after the first few months, and these children outgrow any further adverse reactions.

However, if your baby is experiencing more persistent symptoms, it's important to consult their pediatrician. Your infant might be allergic to their formula if symptoms include:

  • Coughing
  • Wheezing
  • Difficulty breathing
  • Severe vomiting
  • Skin rashes or hives
  • Swelling of the face, lips, or tongue

What is the Difference Between Formula Intolerance and a Formula Allergy?

Many parents will try to alleviate symptoms by immediately changing the baby's formula, which can worsen the situation. Understanding the difference between intolerance and allergy is crucial:

Formula Intolerance:

  • Caused by the digestive system's inability to break down certain ingredients.
  • Symptoms like gas, diarrhea or constipation, excessive crying, spitting up, and fussiness.
  • Usually resolve after the first few months.
  • Children typically outgrow these reactions.
  • Not life-threatening, though uncomfortable.

Formula Allergy:

  • Caused by the immune system reacting to proteins in the formula.
  • Can include hives, swelling, digestive issues, and respiratory problems.
  • Symptoms can range from mild to severe, including life-threatening anaphylaxis.
  • May require immediate medical attention and long-term dietary management.

What to Do if Your Baby is Formula Intolerant

When to See Your Pediatrician

If you think your infant is allergic to the formula you are feeding them, seeing their pediatrician is necessary. Most babies with formula intolerance or allergy symptoms should see their pediatricians immediately. This way, they can help determine whether intolerance or common food allergies are causing the issue before the child has any severe symptoms.

Finding the Right Formula

The baby's pediatrician will recommend how to help with the intolerance. You may have to try several different brands before finding the one your baby tolerates best.

  • The physician may also suggest mixing the new formula with some of the old to help make the transition easier. Taste is a significant factor in your baby's tolerance.
  • You may want to try breastfeeding your baby or pumping to feed your breast milk in a bottle. However, if you choose this option, you must first avoid eating or drinking the food allergen that has caused your baby's symptoms. Cow's milk protein, soy, or other allergens can pass through your breast milk and cause the same allergy symptoms for your little one. After eliminating these from your diet, human milk can be soothing and help your baby get all the nutrition they need.

Your pediatrician can help determine which ingredients in the formula are causing the allergic reaction and recommend another formula more compatible with your child's nutritional needs.

How Do You Tell If Your Newborn Is Allergic to Formula?

When you see your pediatrician, the doctor will most likely ask you questions about the formula your baby is taking and your family history, then examine your baby. They may also want to test samples of your baby's blood or stool.

The child's doctor can often diagnose food allergies based on a patient's medical history, physical examination, and test results. They can help determine which ingredients in the formula are causing the allergic reaction and recommend a formula more compatible with your child's nutritional needs.

How to Address a Formula Allergy

Recognizing Anaphylaxis

The symptoms of anaphylaxis in an infant may include:

  • Difficulty breathing.
  • Swelling of the face, lips, or tongue.
  • Abdominal cramping.
  • Nausea or vomiting.

If your baby is experiencing symptoms of anaphylaxis, call medical emergency services immediately.

Emergency Treatment

If your child has a severe allergy, you might need an Epi-pen to treat an allergic reaction. Carrying these at all times is essential to your baby's well-being.

Long-term Management

The treatment for a formula allergy typically involves avoiding the ingredient causing the severe reaction and using a hypoallergenic formula. This will address your child's digestive problems or allergic symptoms without causing any other health problems.

When introducing a different formula to a baby with a known allergy, it's crucial to do so under medical supervision. Start with a small amount and gradually increase it over time while monitoring your baby for signs of an allergic reaction.

When to Seek Professional Guidance

An allergic reaction is not something that you want to happen to your child. Most babies with formula intolerance or allergy symptoms should see their pediatricians immediately.

Working with a Registered Dietitian

A registered dietitian can help create a diet for children over one year old with food allergies. This is usually done after formula milk is no longer ingested, but the ingredient that initially caused an allergic reaction as an infant may still trigger food allergies in older children.

They can help you plan a nutritious diet to support your child's growth and development and guide you in managing food allergies and intolerances. Always read food labels carefully to ensure products do not contain the ingredients that cause your child's symptoms.

⚠️ Emergency Symptoms: When to Call 911 Immediately

Your infant might be having a severe allergic reaction if symptoms include:

  • Difficulty breathing
  • Wheezing
  • Swelling of the face, lips, or tongue
  • Severe vomiting
  • Abdominal cramping
  • Nausea or vomiting (in combination with other symptoms)

If your baby is experiencing symptoms of anaphylaxis, call medical emergency services immediately. These symptoms can range from mild to severe, which can include life-threatening anaphylaxis.

How to Make a Bottle of Infant Formula

Proper formula preparation is important for all parents, especially those managing formula intolerance or allergies.

Preparing Your Equipment

First, wash the bottles, rings, and nipples after each use. Clean them in hot, soapy water, then sterilize them in boiling water. Second, let the bottles, rings, and nipples dry on a clean dish towel or paper towel.

For parents managing formula changes frequently, automated cleaning tools like the Momcozy KleanPal Pro Bottle Washer and Sterilizer can save time and ensure consistent sterilization with 9 cleaning modes for hands-free bottle washing, sterilizing, and drying.

Storage Guidelines

  • You can make bottles and store them in the refrigerator for 24 hours, but you must discard the formula after that time to prevent bacteria from growing.
  • You can cover and refrigerate open containers of ready-to-feed formula or formula prepared from concentrate for 48 hours, but then they must be discarded.
  • To ensure your child gets the best nutrients from their formula, check to see that it is within its "use by" date. The manufacturer guarantees that it will be high quality and contain the nutrients your baby needs until that expiration.

Types of Formula

Your standard formula comes in three types:

  1. Powdered
  2. Concentrated liquid
  3. Ready-to-feed

Follow these simple steps to get the formula ready for your baby to eat. Whatever form you choose, follow the directions carefully.

Mixing Instructions

Use clean water from a source free of bacteria or other germs that cause disease. The water is used to mix the powdered formula or to dilute the concentrated liquid. Do not use too much water, as this can harm your baby. No water is needed for the ready-to-feed formula.

Mixing Powdered Formula:

  1. Measure the indicated amount of water into a clean bottle (never mix in another container). For infants under two months or those at high risk, boil the water and let it cool before adding the formula.
  2. Add the correct number of level scoops of the powder using the scoop provided in the canister.
  3. Add the nipple, ring, and the cap.
  4. Shake well to mix.
  5. Check the temperature of the formula on your inner wrist to ensure it is not too hot or cold. Bottle warmers with precise temperature control, such as the Momcozy Portable Breast Milk & Water Warmer, can be especially helpful. It is designed for travel and heats water to 104°F in just 3 minutes, ensuring you have the perfect temperature for formula anytime, anywhere.

  6. If the formula is not consumed within one hour, discard any remaining formula. Never reuse leftover formula from a previous feeding.

Mixing Concentrated Formula:

The process is the same as for powdered formula, but you add a liquid concentrate to the water instead. Shake well and warm the bottle before feeding.

Ready-to-Feed Formula:

This formula is recommended for babies with a high risk of infection. Simply shake the container, pour the right amount into the bottle, and warm it as needed.

Protect Your Baby’s Comfort

It's important to identify and address the causes. If it is a formula allergy, your pediatrician can provide recommendations to help your baby feel comfortable without compromising their health.
