Signs Formula Doesn’t Agree with Baby | The Milky Box

Seeing your little one in distress can be challenging as a parent, and not knowing how to help can be even more difficult. If you're bottle-feeding your baby, it's natural to worry that the formula you're using might not be the best fit for them.

In this article, we aim to help you recognize the signs that your baby's digestive system needs a change in diet and to give you tips on dealing with any symptoms of formula intolerance.

Common Symptoms of Formula Intolerance

Identifying when a baby is not tolerating formula can be challenging for parents. Although crying, burping, and fussiness are common in newborns, if these symptoms occur more frequently than usual, it may suggest that your baby is experiencing discomfort due to the formula.

Let's look at some symptoms beyond the usual daily worries that could indicate that your baby is having trouble tolerating formula:

● Frequent crying and fussiness following feedings

Colic signs

● Gastrointestinal issues (gas, bloating, constipation, or diarrhea)

● Noticeable weight loss or poor weight gain

● Extra reflux symptoms like excessive spit-up

● Mucus or visible blood in stool

● Allergic reactions (rashes, hives, eczema)

● Vomiting

You can quickly identify signs of formula intolerance by getting an expert opinion. A pediatric nutritionist working with your medical provider can help you better understand your baby's symptoms, identify their cause, and find the best solution, which may include formula changes.

Possible Reasons Why Infant Formula Disagrees with Your Baby

It's important to understand that formula-fed babies may develop digestive sensitivities for various reasons like lactose intolerance, cow's milk protein allergy, or an immature digestive system. 

These things can be hard to predict and may cause allergic reactions or digestive problems, so it's always a good idea to keep an eye on your little one's health and get help early if there are any issues.

In addition to the different types of symptoms that emerge, the symptoms themselves may come on rapidly or slowly, taking anywhere from hours to days to show up. Rapid onset symptoms include hives, mouth or throat swelling, wheezing or shortness of breath, and anaphylaxis.

Lactose Intolerance

Lactose intolerance is a medical condition that makes the digestion of lactose, a sugar present in milk and other dairy products, challenging. Lactase is an enzyme produced by the cells lining the small intestine that usually breaks down lactose. 

The inability to produce enough lactase has various causes, including genetic and non-genetic factors.

Milk Protein Allergy 

Cow milk allergy is a common allergic reaction in infants and young children. It occurs when a baby's immune system mistakenly identifies cow milk protein as harmful and responds by producing an allergic reaction.

It is good to know that most children outgrow this allergy by the time they reach school age, and the symptoms can be managed with the help of a healthcare professional.

Immature Digestive System 

Another essential factor to consider is the immaturity of your baby's digestive system. An underdeveloped digestive system may cause carbohydrate malabsorption, leading to the fermentation of sugars in the colon and increased levels of gas in the body. This can result in pain and discomfort for babies.

It is worth noting that formulas contain ingredients like corn syrup, starch, or maltodextrin, which may be difficult for babies to digest.

My Baby is Not Doing Well on Baby Formula  

If you notice that your baby is experiencing more than everyday digestive issues, it may be a sign of food allergies. Keeping a feeding log can be very helpful in determining the cause of these symptoms, which you can share with medical practitioners.

Recording the time of feedings, the onset of your baby's symptoms, and how long they last can provide valuable information to the medical practitioner. The more details you provide, the more it will help them determine whether switching formulas is needed.

When Will You Know Your Baby is Having an Allergic Reaction to Formula?

Various symptoms can emerge due to an allergic reaction, which may appear quickly or gradually over hours to days. There are rapid and slow-onset symptoms to watch for.

Slow-onset allergy symptoms:

● Colic, abdominal cramps

● Bloody stool

● Diarrhea

Rapid onset allergy symptoms:

● Hives

● Wheezing

● Itching around the mouth

● Swelling of the lips, tongue, or throat

● Coughing or shortness of breath

● Vomiting

● Anaphylaxis- characterized by difficulty breathing, a flushed face, a swollen throat, itching, or airway constriction.

Finding a New Baby Formula: What to Consider
