Best Formula for Constipation and Gas 2023 (for Gassy Babies)

What causes constipation? 

Constipation in babies is a very common thing and is rarely a serious health issue. It ultimately boils down to what you are feeding your baby on. The good news is that most times, it is easy to eliminate constipation by investigating the cause and making the necessary adjustment.

Constipation in a breastfeeding baby is unusual, but when it happens, it’s probably because you fed on a substance the baby is allergic to. If constipation is frequently occurring, a pediatrician can assist in helping you to identify the culprit in your diet.

For formula-fed babies, constipation is much more common and usually results from making a poor choice of formula that is not suitable for the baby. For instance, you could be feeding your sensitive baby on a formula with cow milk which they find the milk proteins hard to digest. Or you could be feeding them on a formula with ingredients like soy, which they are allergic to. 

Another factor you want to consider is, how well you are mixing the formula; if you don’t follow the instructional guide on the formula, or reduce the amount of fluid you use, most likely, it will lead to constipation.

Dehydration is also another cause; your baby just like you lose water through sweating, so if you don’t hydrate them well, constipation could occur.

At some point, a mother introduces the baby to solid food; sometimes, a bit too soon when the baby’s digestive system is not mature enough to handle solid food, this results in constipation. For a smooth transition, doctors recommend introducing soft fiber-rich foods like fruits and vegetables or juice for hydration.

In extremely rare cases, a baby could have nerve or structural defects in the large intestine that could be causing constipation and these problems can be dealt with by medical experts.

Why Certain Formulas Can Make A Baby Gassy

There are many reasons why a formula would make the baby gassy. Most formulas are made of cow’s milk or soy. A baby that is allergic to these products could experience stomach gas as a result.

Also, there are a lot of babies who have lactose or milk protein intolerance if they are fed with a formula based on cow milk, gassiness will be inevitable.

Other times the baby is sensitive to the ingredients in the formula, usually the proteins. Because the digestive system of the baby is not mature yet, the baby sometimes finds it hard to digest these proteins, this results in gassiness.

Gas can also result when the baby sucks in too much air if the feeding bottle is not angled correctly, causing the baby to suck in the air along with the milk. Ensure the nipple is filled with milk always when feeding.

Symptoms Of Formula Intolerance

  • The baby might have diarrhea or loose, watery stools
  • The baby looks uncomfortable when feeding or refuses to feed altogether
  • The baby becomes gassy, spits up, or vomits after feeding
  • Excessive crying and crankiness for extended period without any apparent cause

Formula for Constipation Guide

How To Know Your Baby Is Experiencing Constipation:

Not pooping for long periods

If a baby stays beyond five days without a bowel movement, they are most likely constipated.

Passing a hard stool with discomfort

Hard stools usually are accompanied by discomfort; the baby might be crying or sometimes also appear to be red on the face from straining. Other times you could notice the poop having bloodstains when constipation is severe.

A hard belly

If you gently press on the baby’s tummy and it feels harder than usual, and they haven’t pooped in a while, the baby may be constipated.

Ways To Help Your Baby With Gas

If you have been feeding your baby with a gentle formula, but they are still becoming gassy from time to time, here are some tips you can employ:

Burp more often: a lot of moms wait until the baby stops feeding to do burps. It would be helpful if in between feeding, the baby had more burps.

Do leg pumps: lay the baby on their back and do a bicycle pump; the baby will be able to release any trapped gas.

Use gas drops: there are many gases relieving drops in the market that can help your baby with no harm.

Angled bottles: these bottles have vent holes and can help when feeding. They keep the milk flowing while preventing bubbles that could make your baby gassy from forming.

Use disposable liners:  disposable liners can help to release out all the air from the bottle, before feeding.
