Baby formula is liquid nutrition designed to mimic a mother’s breast milk when the milk isn’t available. Most formulas use cow’s milk as a base for protein and to better resemble a mother's milk, but some may be made from soy.

While it’s globally recognized that breast is best, baby formula can be a huge help to mothers. It’s a way to feed your baby when your milk supply is low, and it can help babies with very sensitive stomachs get the nutrition they need without worrying about allergens or introducing difficult foods.

If you’re new to formula, there’s a lot to learn. That’s why we’ve put together this expert buyer’s guide to answer some of the most common questions about giving your baby formula and to highlight what goes into the best baby formulas.

Baby formula FAQs

Whether you choose formula or breastmilk can be quite a contentious issue. Because of the disagreement, there’s some misinformation floating around that often sticks in our minds without us realizing it. It's important to make an informed decision about the first foods that your baby will eat.

Before going over some of the best formula products, let’s go through a quick set of frequently asked questions.

What ingredients are used in formula?

Most baby formulas use cow’s milk as a base for the recipe, but some allergy-free and vegan formulas use a soy base. Formula is then fortified and made more easily digestible with:

Ingredients that fortify baby formula

  • checkIron
  • ​checkVegetable oils
  • checkDHA/ARA
  • checkPrebiotics
  • checkPrebiotics

Individual formulas have different ingredients lists, particularly when you’re looking at specialty formula. However, all formulas sold in the U.S. are nutritionally equivalent because every formula manufacturer has to follow the very strict guides required by both the U.S. Formula Act and the Food and Drug Administration.

Does it have lactose or dairy?

Formula is designed to mimic breast milk as closely as possible. Cow’s milk contains lactose and dairy, but non-cow’s milk formulas may be lactose- and dairy-free.

How long has baby formula been used?

Baby formula was developed and patented by Justus von Liebig in 1865. Prior to the use of formula, some mothers relied on wet nurses as an alternative to breast feeding; the practice has been in use for thousands of years and was used in Ancient Egypt, Greece, and Rome.

How warm should formula be?

Formula can be warmed to whatever temperature your baby prefers. It’s fine to give them room temperature or cold formula.

Do you need boiling water?

You don’t need boiling water to make formula. If you do, make sure the water cools until it’s lukewarm and then use it to make formula.

Never microwave a bottle before giving it to a baby. If you want to warm a bottle, run it under a hot tap or place it in a bowl of warm water to raise the temperature.

What water is best for formula?

Ideally, you’ll use low-fluoride water, whether that’s tap water or bottled water. It’s also possible to buy bottle water specially formulated for formula use.

If you use tap water, run the cold tap for a few moments before collecting water. The CDC also recommends boiling tap water before using it to make formula.

When should babies be weaned off formula?

Babies can be weaned off formula when they’re ready: between 10 months and one year. By their first birthday, they should rarely drink from the bottle.

Can you switch baby formulas?

Changing formula brands won’t hurt your baby, but they may be cranky as they adjust to the different tastes.

Can babies develop a formula allergy?

Babies can develop formula allergies; however, allergies are sometimes mistaken for lactose intolerance.

The most common signs of a formula allergy include eczema, hives, difficulty passing gas, and fussiness after eating.

Can you travel with baby formula?

Yes, you can bring an unlimited amount of powder with you wherever you go. You can also bring bottles of liquid formula, but it’s likely your bottles will be tested.

Types of baby formula

There are three main types of baby formula in circulation. These types represent the form the product comes in:

Powdered formula comes in a can with a scoop, and it’s the most economic formula option available for formula feeding.

Concentrated liquid is poured from a contained. These products are more expensive than powdered formulas, but they’re great for when you’re travelling over long periods of time or if you’ve left your little one with a sitter. Because it’s concentrated, it needs to be diluted with water; bottled water works well for this.

Ready-to-useformula is known for its convenience – you don’t even need water. Ready-to-use formula is the most expensive, but it’s not only easy to use when you’re out and about, but it’s less likely to leave your babe constipated than powdered formula.

While most baby formulas will come in one of the three forms listed above, there is a vast number of specialty baby formulas on the market including:

Cow’s milk protein baby formula is the most common type of formula. Designed to imitate a mother’s milk, these formulas use cow’s milk as a protein base.

Organic non-GMO baby formula is made with organic products and without the use of GMO ingredients. These formulas are often dairy-based, using cow or goat milk as a way to model the formula after natural breast milk. Due to the lack of possible pesticide contamination, organic baby formula reduces the risk of any harmful side-effects on your baby’s health.

Soy baby formula replaces the cow’s milk base with a soy base to add protein and remove both dairy and lactose from the mix. Soy formulas often replace lactose with glucose. Note that soy-based baby formula is not recommended for premature babies. However, those with certain health conditions like lactose intolerance and galactosemia would benefit from soy-based formula.

Dairy free formulas are given to babies with milk allergies. These may include soy formulas, but between eight and fourteen percent of babies allergic to cow’s milk won’t tolerate soy either. Other dairy-free formulas include amino acid formulas, which are made of proteins broken down to a simple form.

Hypoallergenic formulas are partially hydrolyzed, which means the milk protein in the formula is partially broken down making the formula easier to digest.

How to make baby formula

Making a bottle of formula is relatively simple.

Start by washing your hands and finding a sterilized bottle, nipple and cap.

Read the instructions on the formula and add the required amount of water for the size of the bottle for the serving you want to make. Then add an unpacked scoop of the formula or the correct amount of formula concentrate to the bottle according to the directions on the packaging.

Mix by putting a cap on the bottle and shaking thoroughly.

Feed the baby right away or store it in the refrigerator or a cool storage container.

Other Baby Formula Brands to Consider

Similac Pro-Total Comfort Infant Baby Easy to Digest Formula

Similac has always been on top of the game when it comes to formula milk and this supplementation is nothing short of the brand’s standards when it comes to quality. It is non-GMO and has OptiGRO, the brand’s nutritional trademark.

Most of all, it contains 10 percent more probiotics compared to the basic Similac Advance formula. So, you don’t have to worry about hard stools which is common in breastfed babies who are supplemented with formula milk.

Switching from breastmilk to formula

Many mothers choose to move from breast to bottle in the months after the birth of their baby. Some of the most common reasons for supplementing breastfeeding with formula include:

  • checkLow milk suppy
  • checkPumping isn't an option
  • checkYou need extra sleep

Whatever your reason and whenever you choose to transition, you’ll find that weaning from the breast to formula is rewarding but also comes with its own set of challenges.

Both you and baby will be conscious of the change, and it’s important for both of you to work together to wean.

Instead of switching complete, start by switching one feed at a time to the bottle. After a few days, you can eliminate another breastfeeding session and replace it with a bottle feed.

Avoid switching out sessions when your baby is particularly hungry. Your little one won’t know how to use a bottle, and hunger leads to frustration which may lead to rejection. You might also ask someone else to introduce the bottle for less resistance; your baby expects your breast and may be upset if you introduce such a dramatic change.

How we choose the best formula

After nursing children of my own, I learned quickly that every baby has different tastes and different tummies. The right formula for my first born was quickly rejected by my second child with no explanation. Finding the right formula is frustrating, and no one likes wasting an entire tin of powder because, after three bottles, your babe just won’t eat it anymore.

That’s why we put together a range of different formulas at different budget points that all focus on being easy for baby to digest. From birth to adulthood, feeding time is time for your family to bond, so it should be as easy as possible to get the nutrition you need!

Tips for buying the best baby formula

Formula is one of the hardest baby products to buy because you can’t know if your little one likes it until they’ve tried it.

Still, you can improve your chances by seeking out formula that:

  • 1Breaks down proteins for easy digestion
  • 2Includes iron and fatty acids required for development
  • 3Uses cow’s milk as a base (unless your baby has an allergy)

If you’re struggling to find the right formula, ask your doctor or pediatrician for suggestions.

Accessories that make formula feeding simple

Formula feeding looks easy, but once you’re preparing and washing an uncountable number of bottles, it starts to wear you down.

We can’t recommend formula feeding accessories enough for simplifying bottle feeding and making your life just a little bit easier.

Formula dispensers

On the go? Formula dispensers carry around pre-measured scoops for formula, so all you need to do is mix and go – wherever you are.

Formula makers

Make bottle feeding at home as simple as possible with a formula maker.

These appliances look like Keurig machines – for formula. They hold powdered formula and filtered water and do the shaking for you. All you need to do is press the button.

Formula mixers

Avoid lumpy bottles and cranky babies with a formula mixer. Mixers combine the ingredients without leaving clumps or sediment behind for a smooth bottle.
