Before you can figure out what’s the best formula for gassy babies, you need to first know what the common causes of infant gas are.

The first problem could be related to your baby’s bottle or the method you use to mix your baby’s formula.

Certain bottles are known to trap excess air, which in turn is swallowed by a baby causing gas bubbles in their belly. 

Shaking formula in order to mix it can also create an undue amount of foam, which is, of course, air and gas.

The second issue could be with your baby; they may simply have reflux. This is also a common problem due to babies’ immature digestive tracts. Food simply backs up into the esophagus and comes back up as spit-up.

Some cases may be so severe that your baby may not gain weight properly. However, most cases are manageable and clear up on their own.

Finally, your baby may have excess gas in their digestive tract due to allergies and food sensitivities. Most of these reactions stem from either milk proteins/lactose or soy components.

A simple change in formula or changing to breast milk can help solve this issue.

Out of all the money spent on baby products – those that are purchased on a regular basis – formula makes up the biggest expense per year. That being said, you want to make sure your formula is cost effective, giving you the lowest cost per bottle.

Keep in mind that certain specialty formulas such as organic, soy-based, and others with special ingredients will generally be much more expensive than standard formulas.

Babies eat a lot so you will probably need to buy your formula in bulk to ensure that you don’t run out when you need it most.

Every formula is different as well, some requiring more or less water or powder to make a single bottle. Pay close attention to how much you are getting with your purchase and how many bottles each canister will make.

Anything that enters your baby’s body should be monitored closely. Their digestive, immune, and nervous systems are severely underdeveloped, and certain ingredients in baby formula can either hurt or help their developing bodies.

Read all the ingredients before deciding on a certain formula.

You really can’t go wrong with any Gerber products. They’ve been trusted for years by parents nationwide.

It’s no surprise that they have a formula that is specially formulated to soothe upset tummies.The Gerber Good Start Soothe formula comes in a 22.2-oz container and is formulated for babies 0-12 months old (stage 1).

It is made with a special carb blend that is only 30% lactose to help ease discomforts due to milk sensitivities.Some of the benefits of this formula include L reuteri, which is proven to reduce colic (fussiness and gas) by 50%, DHA for brain development, and 2’-FL HMO (Human Milk Oligosaccharide), a prebiotic to boost immunity.

This formula is also GMO-free and is not made with any artificial growth hormones.Gerber Soothe is one of the few baby formulas that doesn’t contain corn syrup solids. However, it does contain corn maltodextrin.

The difference is that maltodextrin is formulated to have 20% less sugar content.The biggest downfall to this formula is that it seems to be a bit tricky to mix.

Not only are the instruction proportions slightly off, the formula remains a bit foamy and clumpy after shaking.

Perhaps due to the consistency, many parents have said their babies have also experienced constipation with the use of this formula.

The prebiotic 2’-FL HMO helps to support immune health.Just as with many baby formulas, there is always the chance of your baby becoming constipated.

Other than that, there aren’t many negative things to say about this other than the fact that it does contain corn syrup as most baby formulas do.

As a result, it reduces gas and fussiness due to lactose irritation.

It also contains DHA and choline to promote healthy brain development, and its vitamin blend supports the immune system.Being soy-based, it is a bit more expensive than standard baby formulas.

With its inclusion in this formula, it was found that 90% of infant colic was reduced within 48 hours with the use of this formula. 

It has also been shown to prevent common allergies such as asthma and eczema by 50%.There are mixed opinions on the consistency of this formula.

Some say that it mixes really well while others complain that it’s too clumpy and foamy. 

You may be taking a chance with this formula.The biggest downside to this formula is the fact that it is very expensive.

The container is pretty small compared to others (19.8 ounces) and only makes about 31 4-oz bottles making it the least cost efficient formula on this list.

However, the benefits of this formula may outweigh the cost.
