Rush to your baby’s doctor if you observe any of the above symptoms in the baby when formula fed. Your baby’s pediatrician may ask several questions about the baby’s formula milk and the baby’s response after feeding formula milk.
The doctor might proceed with the baby’s stool test, and other tests might be performed to diagnose if your baby is allergic to milk or if it’s the intolerance they are suffering from.

How to Treat Allergic Reactions in Formula Fed Babies?
Several treatments can be done to relieve formula intolerance caused in most babies. However, we have listed the most common ones.
Switch to Another Formula for Newborn

This often solves the issue. The formula for newborns features several potential ingredients that might be the agents causing intolerance. These include soy, cow’s milk, and rice proteins. If your baby is allergic to any of these, they need to switch to hypoallergenic formula, for example amino acid based formula and soy formula. Each milk protein is broken in a hypoallergenic formula, helping your baby’s digestive system to digest them conveniently.
Consult your baby’s doctor for the formula milk that will best suit them, helping them with intolerance. You can’t directly switch to another formula; first, you must formula feed your baby with a mixture of new and old formulas.
Your pediatrician will ask you to increase the amount of new formula gradually with time. This way, your baby will become used to the new taste, and switching to it will become easier. You must watch out for the symptoms of intolerance while continuing to increase the amount of new formula gradually.
Consider Breastfeeding
Most mothers choose formula feeding because their breasts don’t produce enough milk or face other issues like plugged ducts or sore nipples. If that’s the case, lactation consultants or healthcare professionals might help you.
Breastfeeding will be a game changer in this situation, helping your baby with discomfort and providing them with all the necessary nutrients. You might go for pumping breasts and give breast milk to your baby in a feeder.

Note one thing; if you are opting for breastfeeding, you must avoid soy, cow’s milk, or any other potential allergen responsible for sparking intolerance. It’s because these might pass to the baby through your breast milk.
Go for Oral Rehydration

When suffering from formula intolerance, your baby will end up dehydrated because of frequent vomiting, diarrhea, or less consumption of formula for newborns. If that’s the case with your baby, add ORS in your baby’s diet.
ORS, a drink boasting sugar, salt, and minerals, can help replace body fluids. Ask your baby’s doctor what type of ORS you should use and the right amount.
Use a syringe to feed your baby ORS. Small amounts are given if your baby has been vomiting. Does your baby vomit after feeding ORS? Wait for thirty minutes and try again.
When to See Doctor?
Talk to your doctor if your baby has a fever, the rash is worsening, has vomited more than twice in the past 24 hours, suffers from breathing problems, or more. Do keep a check of the bowl moments and urine, too; if your four or more days older baby had fewer than three bowel moments and had wet fewer than six diapers daily, it’s time to see a doctor!
Other signs include the baby sleeping more than usual, being very irritable, and being much more difficult to console a crying baby.

Wrapping Up
Formula intolerance is a relatively less severe allergic reaction to formula feeding than the milk protein allergy. Most of the time, switching to another formula for newborns will relieve intolerance; if not, consult the child’s doctor.
That was all about the formula intolerance babies suffer from; its causes, symptoms, treatment options, and more.
