Eight Signs Your Baby Has a Milk Allergy

Rashes, colds and upset stomachs are common baby ailments. But the occurrence of one or more of these symptoms can signal a serious allergy. If unrecognized, these symptoms can make an infant miserable and malnourished.

eight-signs-your-baby-has-a-milk-allergy.jpgMore than 100,000 babies each year suffer from milk allergy. The condition causes digestive, respiratory and/or skin problems and is often difficult to recognize.

“These babies cannot process the complex protein chains found in milk-based baby formula. And many also react to soy-based formulas,” says Dr. John Moissidis, a Board certified pediatric allergist at The Asthma Allergy Clinic in Shreveport, La.

Infant milk allergy is treated by either eliminating the milk proteins from the nursing mother’s diet, or by replacing the regular formula with an amino acid-based formula.

“An amino acid-based formula is safe for babies with milk and soy allergies because it is comprised of non-allergenic amino acids, the building blocks of protein, instead of partial or complete protein chains found in other formulas,” says Sarah O’Brien, nutrition specialist for Nutricia North America, the manufacturer of amino acid-based formula Neocate.

This specialized formula does not require a prescription, but infants taking it should be under the care of a physician.

Here are eight signs, provided by Dr. Moissidis, to help parents of infants identify a potential milk allergy.

1. Diarrhea
Diarrhea is common in babies, but if it is persistent (an average of two to four times a day for more than five to seven days) and/or if there is blood in the stool, it could signal a more serious milk allergy.

2. Vomiting
Babies often spit up bits of food, but vomiting beyond the typical mealtime regurgitation should be examined by a doctor. Reflux symptoms, such as spit-up and difficulty swallowing, can also be milk allergy symptoms.

3. Skin Rash
There are many causes for infant skin rashes like eczema. Milk allergy is one possible cause, especially if the rash occurs along with some of these other symptoms.

4. Extreme Fussiness
Every baby cries, but crying continuously and inconsolably for long periods of time is abnormal. When there is no apparent reason, this is usually called colic. Sometimes this extreme fussiness is actually caused by the gastrointestinal pain resulting from an allergy to the proteins found in milk.

5. Low or No Weight Gain
Most infants double their weight by six months and triple it by 12 months. But when babies are not getting the nutrition they need because of excessive diarrhea and vomiting, they are unable to grow like they should.

6. Gassiness
All babies have gas, but when it occurs along with several of these other symptoms, it can also signal an allergy to milk proteins.

7. Respiratory Problems
Colds are common for infants, but wheezing, struggling to breathe and developing excess mucus in the nose and throat is not. For some kids, these respiratory problems can be the baby’s reaction to the protein found in milk.

8. Failure to Thrive
Babies with milk allergy often suffer from a lack of proper nutrition characterized by dehydration, loss of appetite and lack of energy. This overall failure to thrive is often the result of the effect of the other symptoms effect on the infant’s body.

Parents can take the allergy test and learn more about infant milk allergy and amino acid-based formula at

Hello! My grandson is a month old and constantly cries. At first I thought it was colic but he cries uncontrollably for no reason. He gets fed and never seems satisfied. He moans and groans and is very gassy and spits up more than usual. We have him on Similac Sensitive but I was thinking of giving soy milk a try. What do you all think this could be?

My son was born just over 3wks early and his lungs were not developed…had to stay in NICU for 3wks where i pumped milk and mixed with formula due to my supple being low. When we finally took him home I was barly producing enough breast milk for 1/4 of what he was consuming and so switched over 100% to formula. Baby is now 9 months old and had continually had the above symptoms and has been to the ER three times and several extra doc appointments for respiratory issuse, rashes and reflux. We always associated that these respiratory issues… Read more »

I agree with Heather. My son is allergic to milk, wheat, soy, eggs and peanuts. I have been on an elimination diet for about 6 months and it have not reduced my milk supply. His Pediatrician is wonderful and so we are having him tested for allergies. He has really bad eczema, hives and was itchy all the time. The elimination diet has helped reduced the eczema and now we are waiting for narrow down the list of allergens. We are mainly on a rice diet and he is growing well. He was also given Elacare formula which he tolerates… Read more »

I just wanted to correct one of the comments posted above. If you are breastfeeding and have to do an elimination diet, your supply does not always decrease. I know a lot of breastfeeding moms who have had to cut out allergens from their diet and had no problem with supply. My own son has a dairy sensitivity and I cut out all dairy from my diet. I’m still breastfeeding him at 11 months with no supply issues. It’s hard to give up dairy, but well worth it when it helps your child feel better!

When my son was 3 weeks old, I knew something wasnt right. I was primarily breastfeeding but supplementing with formula, and every day he seemed to be getting worse. He had atopic dermatitus since his 2nd day (when I started him on formula) and it spread all over his body (and the hospital neonatalogist even said was an “allergic reaction to something and she’d be interested to know what it was from.) That was then accompanied by diarhea and he started getting more and more fussy/gassy/restless by the day. About week 3, he started having chest congestion (cracking noises and… Read more »

My baby is 2 months old. When he was born I was breastfeeding him but for personal issues I had to stop. He’s been drinking formula for about a month an a wk .His pediatrician has changed his milk 3 times. From Good Start Green Label, to orange, Now to Soy formula and since he started he’s been constipated and a really badddd rash all over his face and neck. Today I notice that it was starting on his arms and hands. Can he be lactose intolerance just like his father?? and what could all this be coming from?

I am a mother of two. My first child was colic from the day I brought her home from the hospital. She had horrible gas and you could tell she was in pain. I breastfed her for 7 months. I keep telling the doctor something was wrong and all I heard was she was colic and would grow out of it once her digestive tract matured. Needless to say, at four months there was blood in her stools. I was told she had a virus and I argued that she is not sick with a virus. She is at home… Read more »

My son is three months old. He has had a cold since he was born. (congestion, runny nose, cough) He has also had exzema since he was about a month old and also has acid reflux. (test confirmed this) We have had him on nutrimigen, similac allementium, and now ellecare. He has been on the ellecare for over a week and we still have seen no improvement. I have no idea where to go from here. Advice Please……………

My seven month old has been spitting up since birth. Her doc thinks her low weight could be because of a milk allergy and her constant spitting up. He wants me to switch formulas…again and add vitamins and more solids. I am tired of switching formulas since they are so costly and thry tend to upset her tummy until she adjusts. Would it be better for me to just ask for the milk allergy test to at least know for sure?

I agree with the last commenter. We have been to many, many dr.’s, nurses, dermatologists, etc. My son had severe eczema and they all never once thought that it was food related. I’ve been breastfeeding. It wasn’t until I went to an allergist that we found out he was allergic to over 20 things (milk, soy, egg, all nuts, barley, oat, wheat, bananas, tomatoes, yeast, gelatin, etc.). It was a huge challenge but since cutting those things out, he’s clearing up. He also had an anaphylactic reaction from a jar baby food that contained cheese. So be careful! That’s what… Read more »

If you think your baby may have a milk allergy–SEE A PEDIATRIC ALLERGIST!! They CAN and WILL do testing before one year to help diagnose milk and other allergies. My breastfed daughter had “severe reflux” and eczema for months. Only when I let her taste yogurt at 7 months did I find out it was actually a severe (anaphylactic) milk allergy (also eggs and nuts) that none of her 20 or more doctors (NICU and other peds) even considered for her. I ate/drank these allergens every day, all day and never even considered that she may be allergic to something… Read more »

For those of you struggling with the reflux issues…my son was told he would be on meds for years. I finally saw a dr. at the children’s hospital and he said he has dysphagia. The allergist and pediatric gastroenterologist missed this! If your child has reflux symptoms, seems congested/wheezy at times and coughs while drinking a bottle or breastfed, ask about dysphagia. I think it’s more common than people think!

I have been very frustrated with Dr’s lately. My daughter is 8 months old, and we dealt with reflux since she was 6 wks old. Got tired of all the co-pays and the “she just has a virus”, “she has croup”. The list goes on and on. So, I put her on Similac Alimentum, a hypoallergenic formula, and the reflux was at least tolerable. She even threw up the breastmilk. About a month ago, she outgrew the reflux, so they changed her formula to a milk-based..Similac Advance. She had a cold from cutting teeth, but she began not eating…. I… Read more »

okay sorry but my child is 9 months old and because I was cautious and trusted deeply in mothers intuition, I immediately changed her formula to soy (which by the way worked! no more “acid reflux”) and I insisted my child be tested before the one yr mark for allergy testing! I also without knowing what her allergies were removed all milk and eggs from her diet finally at 8 months she was finally diagnosed with level 7 milk level 5 egg and level 7dust mite allergies…. her symptoms were as follows :: 1)what the dr called acid reflux was… Read more »

My baby has several of these signs, except that he is often constipated instead of having diarrhea. He projectile vomits at least twice a day, spits up more than a small amount every feeding, screams as though he is always hungry and never satisfied, even right after a feeding, has a rash on his face that is NOT the acne he had when he was first born and that is spreading… SO many signs! I had a severe milk allergy when I was a baby and it did not start to become less problematic until I was a teenager. Now… Read more »
