5 Best Formula for Colic and Constipation – 2024 Reviews and Guide

Babies or infants sometimes go for a long period without bowel movements. This is a significant symptom of a colicky baby and constipated baby. What do you do when you discover that your child has some difficulty emptying his/her bowels?

Above all, how can you tell that a baby is constipated or colicky? In this article, we shall be looking at the best formula for colic and constipation.

Understanding Colic

Colic is a severe abdominal pain usually composed of air in the intestine associated with feeding difficulties. Colic sometimes arises due to constipation. Colic isn’t a diagnosis, instead is an observation. So technically, a colicky baby is not a sick baby. He/she instead is a healthy baby reacting to excruciating belly pain.

However, allergies and smoke can also trigger colic more or less. Knowing if a baby is colicky is simple, the baby starts to cry excessively consistently over a specific period.

Pediatricians have identified a method to know if a baby is colicky. They call it the “rule of threes,” crying bouts that start when a baby is about 3 weeks old frequently late in the day. This rule means that babies with a colic cry for three hours a day, for more than three days a week, and this can last three weeks or more.

Causes and Symptoms of Colic

There is no known cause of colic presently and why some babies experience it is still a mystery. Although some theories suggest possible causes. One of those theories is that some doctors see it as a natural developmental stage that babies go through as they adjust to all the different sensations and experiences that come with life outside the womb.

Another theory suggests that colic may be caused as a result of the imbalance of bacteria in the gut of the baby.

Another theory which is a likely cause suggests that colic stems from an imbalance of the brain chemicals melatonin and serotonin. Serotonin makes intestinal muscles of colicky babies to contract. This hormone usually peaks in the evening.

When a baby starts to produce more melatonin generally at 3 to 4 months old (around the same time colic disappears), it relaxes the intestinal muscles and strikes a balance.

It’s worthy to note that colic is only temporary and there are ways of managing it for the time being such as; swaddling, swooshing loudly in baby’s ear, swinging baby, providing a pacifier for the baby to suck, and laying her on her side or stomach. Pediatricians call it the “5 s”.

Understanding Constipation

Constipation is a condition in which bowel evacuations occur infrequently or in which feces are hard and small or where the passage of feces causes pain. As a parent, it will become normal for you to have conversations with your spouse about your baby’s poop.

You begin to notice the timing and patterns at which your baby pass put. Some babies can poop as high as three to four times daily while others poop once or every other day. So it becomes easier to detect when your baby is ill or not. This is how you know if your baby is constipated or not.

Causes and Symptoms of Constipation

We know that infants or babies may go for an extended time without emptying their bowels. Parents find it challenging to ascertain if their baby is constipated or not.

Causes of constipation in babies are due to the immediate switch between a mother’s breast milk and baby formula. Breastfed babies find it easier to empty their bowels since the baby’s system find it easy to digest breast milk.

Once the baby is older, between 3 – 6 weeks old, passing out may take longer than usual. However, it doesn’t mean that the baby is constipated. With the introduction of formulas to the baby, he/she will have fewer bowel movements than a breastfed child. Their stools will be thicker and have a different, more greenish color.

This means they pass out even lesser than breastfed babies. Some may pass out once in a couple of days while others take more prolonged period. Most babies find it difficult to switch between these formulas and breast milk. Hence, they find it difficult to empty their bowels.

Another cause of constipation in babies is the introduction of solid foods after baby formulas or breast milk. A baby digestive system is not well developed yet to digest solid foods, so introducing solid foods immediately will change his/her diet and disturb his/her system. This will eventually lead to constipation.

A baby may also be more likely to become constipated if a parent introduces cow’s milk to their diet.

Cow milk like solid foods is difficult to digest in a baby. Hence the baby experiences constipation. Once a parent notices these signs, it’s paramount to take the baby to a pediatrician as soon as possible. Symptoms that can indicate if a baby is constipated or not:

  •  Stools become infrequent and hard
  •  The belly becomes hard
  • Stool can be a little bit bloody
  •   Hard pellets can be found on stools
  • Since babies find it difficult to empty their bowels, during the process, crying becomes the order of the day
  • Subsequent stools become clay-like
  • Lack of appetite

These symptoms of constipation vary in babies depending on their age and diet. A healthy bowel movement before a baby begins eating solid food should be very soft. Among all the symptoms listed above, hard baby stool before solid food is the most apparent symptom of constipation in babies.

Considerations for picking the best formula for colic and constipation

While looking out for a suitable formula for colicky babies or constipated babies, certain factors determine your choice of baby formula. These include;

Types of Formulas

For colicky babies, there are three main types of formulas available. These are; ready-to-use liquid formula, concentrated liquid infant formula, and powdered infant formula.

The ready-to-use liquid formula as the name suggests comes readily available feed bottles called nurseries. This formula is available in hospitals and is compatible with the mother’s nipples.

Concentrated liquid infant formula is not available as ready-to-use. You have to mix them in an equal quantity of water and formula before feeding. It is cheaper than the ready-to-use method and easy to use.

Powdered infant formula is a more common type amongst the three. You will need to dissolve it thoroughly in water before use, unlike concentrated liquid infant formula. It is the cheapest among the three listed.

Source of Milk

Colic formulas are also dependent on the source of milk or protein. Cow milk is the most common type of milk source but doesn’t go down well with many kids. Most kids are sensitive to it even though a cow’s milk structure is similar to a mother’s breast milk. Except in the case of allergies, cow milk is highly recommended by pediatricians.

The lactose-free formula is suitable for babies as a result of ingestion of cow milk. Soy milk formulas, goat milk formulas are the hypoallergenic formula for babies that are allergic to cow milk or protein.


Most baby formulas in the market have FDA approval. It is still as a parent to ensure that the one you are purchasing is FDA approved. This way, you are sure that you trust the product. You also have to be careful to check if the formula is generically enhanced or not. A genetically enhanced formula can be dangerous to your baby.


If your baby has allergies, you must purchase a hypoallergenic formula.


Don’t just buy a colic formula for your baby, purchase one that will support his/her growth development. Endeavor to look out for formula with extra nutrients like DHA, ARA, or iron for building up of the immune system, brain, and vision development.
