12 Best Baby Milk Formula for Constipation 2023

Neither diarrhea nor constipation is fun for both the baby or the parents. However, most babies will have one or both at some point in the first year. This is usually caused by a problem with their digestive system.. or it could just be a tummy bug.  

But don’t fret, because these baby formulas are known to ease the situation. 

Baby Constipation Home Remedies

If your child is younger than four months old, talk to a doctor or nurse about treatment of constipation. For infants of any age, contact the child's doctor if there are concerning signs or symptoms (such as severe pain or rectal bleeding) along with constipation. 

The following remedies are for infants with constipation who are older than four months..

Fruit juice – If your infant is at least four months old, you can give certain fruit juices to treat constipation. This includes prune, apple, or pear juice (other juices are not as helpful). You can give a total of 2 to 3 ounces (60 to 120 mL) of 100 percent fruit juice per day for children four to eight months old. You can give up to 6 ounces (180 mL) of fruit juice per day to infants 8 and 12 months old. However, do not give juice every day for more than a week or two. Too much juice can be unhealthy for children's overall diet and growth.

Dark corn syrup – Dark corn syrup has been a folk remedy for constipation for hundreds of years. Dark corn syrup contains complex sugar proteins that keep water in the bowel movement. However, current types of dark corn syrup may not contain these sugar proteins, so the syrup may not be helpful. It is not clear whether light corn syrup is helpful.

High-fiber foods – If your infant has started eating solid foods, you can substitute barley cereal for rice cereal. You can also offer other high-fiber fruits and vegetables (or purées), including apricots, sweet potatoes, pears, prunes, peaches, plums, beans, peas, broccoli, or spinach. You can mix fruit juice (apple, prune, pear) with cereal or the fruit/vegetable purée.

Enfamil Nutramigen Infant Formula Reviews
Excellent for babies with milk allergy. Cleared up my daughter’s eczema and rashes within weeks! Very pleased! Makes poo smell awful too so that’s cool, I guess if you’re looking to use your baby’s feces as a weapon or social deterrent.

2. HiPP HA Formula Stage 1, from Birth 600g - Hypoallergenic Baby Milk Formula

HiPP HA (hypoallergenic) Formula Stage 1 from Birth 600g
Buy on Formuland.com

Hipp HA formula is a hypoallergenic formula that is suitable for babies with milk protein allergies. Milk protein can be an important factor to trigger allergies. The Hypoallergenic (HA) protein diet contains milk which is split in simple molecules. This reduces the risk of allergies. The protein formula used in Hipp is completely hydrolyzed and was proven by studies to prevent allergies.

A low-allergen diet cannot give complete protection but reduces the risk of allergies in infants. The HA formula should stay constant for 4 to 6 months in order to produce best results. A small amount of non-hydrolyzed protein can promote sensitivity and destroy the benefits of the low-allergen diet.

Mama Bear Hypoallergenic Infant Formula Reviews
This is the same as the other store-brand hypoallergenic formulas like at Target, Kroger, etc. I’m finding that those places have been low or out lately, so this has been a very convenient alternative source for what is the same formula.

I’ve found that the store-brand does not mix quite as well as Nutramigen, but as long as I shake well, any clumps left at the beginning are gone by the time my daughter finishes her bottle. Huge money saver! Highly recommend this formula!

Gerber Good Start Extensive HA Reviews
You’ve found it! Our poor little guy was diagnosed with a milk protein allergy at 2 weeks old, and we got a sample can of Alimentum from our pediatrician. That stuff smelled horrible and made our son gassy and have reflux. So we switched to the Gerber to give that a try, and wow, night and day difference. I also like that it includes probiotics and MCT oil, and uses non GMO corn, because I felt serious mom guilt not being able to feed him an organic formula. We also add Probiota Infant probiotic powder to one bottle a day, and the gas, reflux and tummy problems are long gone! Can’t recommend this formula enough!

6. Similac Alimentum Hypoallergenic Milk Formula - Best Similac Formula for Constipation

- Has no lactose, but still contains other milk products.
- Uses corn maltodextrin sugar on top of other sugars, overall has more sugar content than Enfamil.

- Cons : Bad smell


Let me start by saying that I hate almost everything about this product, except the fact that it works. We had to switch from regular formula to Alimentum at the recommendation of the pediatrician due to lactose issues causing bloody stool. This worked and stopped the problem almost immediately. He actually enjoyed drinking this stuff for the six months until we could ween him onto other foods.

I'm giving this formula an overall three stars. Five stars for a product that works, and one star for expensive price and the horrible smell.

So thankful for this formula. My infant has FPIES and malabsorption and this is the only elemental formula with 10% more MCT oil than the others and actually helps him gain weight.

My baby was born in March and we tried a lot of formulas. They made him constipated, projectile vomit, or gave him colic all night long. I tried 10-12 different formulas. My pediatrician then recommended I go for soy, since he figured baby had a milk allergy. I didn't want to go that route, so I tried this as a last resort. My baby started to sleep during the night again and he wasn't constipated or vomiting at all. He doesn't even have spit-up with this one. It has been wonderful and he's almost 6 months now. He's growing at a healthy rate and enjoys his milk.

To add, I tried some formulas that smelled so bad I felt I gagged. This one doesn't smell bad at all. The only con is the price and that I can only find it on Amazon or Target.

Before ordering LactoRelief I called Nature's One to inquire about the amount of lactose in it. They said it's less than 1%-that's a big difference! I ordered it right away & our son has been on it ever since. His remaining gastric issues cleared up almost immediately & he's now 3 months old & doing terrific. We'll keep using this formula until he no longer needs formula.

1. Partially hydrolyzed formula vs Extensively hydrolyzed formula

Hydrolyzed literally means “broken apart.” Both formulas require less processing to absorb and are a good option for some newborns or infants who have difficulty digesting full-size proteins or have a history of digestive problems.

However, the proteins in extensively / fully hydrolyzed formulas are smaller than proteins in partially hydrolyzed formulas. And a study showed that partially hydrolyzed formula was found to be less effective than extensively hydrolyzed formula in preventing cow’s milk allergy.

2. How do I know if my baby needs hypoallergenic formula?

Here are 6 signs your baby might need hypoallergenic formula. 

a. Extreme Irritability
If your baby cries for long periods of time, it may be a good idea to discuss this with your doctor. He can evaluate your baby further and help diagnose a cow’s milk allergy. In this case, switching to a hypoallergenic baby formula may help your baby’s symptoms.

b. Family History of Food Allergies
If you or a member of your family has a history of food allergies, your baby is more likely to have one as well. An extensive French study done in 2019 showed a strong genetic link in cow’s milk protein allergies (CMPA).

c. Constant diarrhea / vomiting

d. Your baby has acid reflux (GERD)
Acid reflux is what happens when stomach contents and acid flow back up into the throat. This is a common problem in infants, especially those below 3 months old. Hypoallergenic formula may help reduce the symptoms.

e. Eczema
Your baby’s skin is sensitive, which can make it difficult to tell the difference between dry skin and eczema. Eczema is extreme dry skin that is red, inflamed, itchy, and often cracked. Babies with eczema are more likely to develop food allergies and oftentimes will develop skin symptoms before other food allergy symptoms appear. (Source)

f. Respiratory Issues
If your baby is wheezing or experiencing other respiratory issues, your baby may need immediate medical attention. See a doctor as quickly as possible.

Above all, if you're unsure, best consult a doctor for determining the best formula for your baby.
