What Do I look Out For In A Good Formula Brand?

It can be overwhelming to see so many claims and promises on your baby’s formula box, how do you know what’s best for your little one and what do you need to look out for?

There are several pointers to look out for in a good formula, here are a few pointers. It is important to pick a formula that will help your baby with specific issues such as gas, intolerance, or colic. 


It’s very easy to get sucked in by a formula’s packaging or bright colors and claims. But arguably the most important thing to look out for is the ingredients and minerals included in the formulation.

Ninety-eight percent of infant formula is just protein, carbohydrates, and fat. The protein and carbs have the most impact on your little ones’ tummies when being digested, so it’s important you get it right to avoid discomfort and excess gas for your baby.

It is also important to look out for certain ingredients that are a big no-no. These include corn syrup, high fructose corn syrup & any other added sugars.

You do not need to add any sugar or sweeteners to your baby’s diet and this can cause health issues for them in the future.

Additionally, you should look out for any artificial colorings & synthetic flavors as this has been linked to an increased likelihood of behavioral disorders.

It has also been found that the inclusion of palm oil restricts an infant’s ability to absorb iron content, which is essential for growth, development, and their developing immune system. 


Another important thing to look for when choosing a formula is the brand’s certification. This means the brand has been safety tested and you can rest assured knowing it contains all the right things your child will need to grow healthily.

The first thing to look for is USDA certification. This is the U.S Department of Agriculture, they check all ingredients are grown in synthetic fertilizer and pesticide-free soil, as well as being free of artificial colors, flavors, and preservatives. 

Some further things to look for are;

  • Probiotics – These are vital for ease of digestion and boosting their immune system
  • Safe packaging – Be sure there is no BPA present.

Easy Digestion

Can Drinking Too Much Milk Cause a Toddlers Poop to be White?

Lots of grunting, gas, and discomfort can often be a sign your baby is having trouble digesting its current formula.

Some brands on the market advertise easy digestion, but it is important to figure out what aspects of the formula are causing these issues for your little one.

Most babies can handle cow’s milk formula without any issues, but a small percentage may not be able to for a couple of reasons. This could be lactose intolerance or a possible underlying allergy.

If you suspect either of these issues is to blame you can contact your pediatrician for more advice and maybe try switching over to a lactose/dairy-free formula mix. 

Possible Allergens

As we just mentioned, it is important to not rule out the chance your baby could be allergic to certain ingredients in your current formula. Signs of this include;

  • Excessive gas
  • Obvious discomfort shortly after starting/ finishing a feed
  • Unusual stools
  • Frequent spit-up
  • Rashes
  • In severe cases, anaphylaxis

There are several things your little one could be allergic to in the formula, from lactose to soy or even wheat.  Your doctor should be able to give you more information on allergens if you feel this is something your baby may be suffering from.

How do you know if a baby needs sensitive formula?

Some signs to look out for that may indicate that your baby has an intolerance to their current formula can be;

  • Diarrhea
  • Blood or mucus in your babies diapers
  • Colic
  • Trouble gaining weight
  • Pulling their legs up (this is a sign of abdominal pain)

If one or more of these symptoms happen on a very regular basis it may be worth a trip to your doctor and a change in formulas.

What is the difference between sensitive and gentle formulas?

There are several differences in these two types of formulas but the main difference is the target audience. Sensitive formulations are for babies with a sensitivity to lactose, whereas gentle formulas are to help babies with digestion & gas which leads to fussiness and crying.

How long does it take for a baby to get used to formula?

When swapping formulas it is important to do it gradually so you don’t upset your baby’s tummy further.

Make sure to spread the change out over 3-5 days and monitor their diaper output as a real telltale sign of how their tummies are handling the swap. Some babies may have no issues and swap formula well without any trouble.

How do I know if the formula is making my baby constipated?

It will be quite obvious and sometimes distressing when your baby is constipated. Their bowel movements will appear hard like pellets and you may find blood when wiping.

As babies can’t communicate with you, the tell-tale signs will be an arched back, red-faced and crying from the discomfort. 

How many times a day should my formula-fed baby poop?

Every baby is different but as a general rule, 3-4 times a day is the average normal rate for a formula-fed baby. As long as they pass them without any struggle, you shouldn’t worry.

If your baby goes longer than 5 days without pooping, you should contact your pediatrician for more help and advice.

The Final Thought

Hopefully from this lineup, you can find some answers to your questions of why your baby might be extra fussy and gassy.

Those early days are hard but remember, if you have any doubts you should always consult your doctor or pediatrician for more advice as to the root cause of your little ones’ issues.
