While all infant formulas help to nourish your baby, there are different types. Some are specially formulated to support specific needs your baby may have.
If you need help choosing a formula, talk to your doctor. You can also compare options with our Formula Finder.
The different types of baby formula and toddler drinks
Before trying a new feeding option, consult your child’s doctor for a recommendation based on their needs. Infant formulas provide complete nutrition to support your baby’s growth and development and have important vitamins and minerals.
Milk-based, iron-fortified formula
This is the most common type of formula, and it’s often recommended by doctors. If this is your first time feeding with formula, it’s a good place to start. The carbohydrates in these formulas come from lactose, which is the major carbohydrate in breast milk.
Our closest formula to breast milk is milk-based Similac® 360 Total Care® formula. Another milk-based option is Pure Bliss® by Similac®, which starts with fresh milk from grass-fed cows and has been imported from Europe since 2016.
Formulas for fussiness, gas & mild spit-up
- Sensitive infant formula
If your little one shows signs of a sensitive tummy, like fussiness, gas, or mild spit-up, sensitive formulas are designed to help. They contain carbohydrates such as maltodextrins, instead of lactose, making them suitable for infants who may be sensitive to lactose.
Try Similac® 360 Total Care® Sensitive, our closest sensitive formula to breast milk, which was created for babies with sensitive tummies.
- Partially hydrolyzed protein-based infant formula
If you’ve tried a sensitive formula and your baby is still showing signs of fussiness, gas, and mild spit-up, partially hydrolyzed protein-based formulas may help. This type of formula is also good for babies with lactose sensitivity.
Similac Pro-Total Comfort® has partially hydrolyzed whey protein and is great for babies who have difficulty tolerating other milk-based formulas.
- Soy-based formula
If your baby has fussiness or gas when feeding with other formulas, you might want to try a soy-based formula. Soy-based formulas have been clinically shown to help reduce fussiness and gas. Your doctor may also recommend a soy formula if your baby has galactosemia. Vegan families often prefer a soy-based formula for their babies.
No other soy-based formula has been studied more than Similac® Soy Isomil®, which supports normal growth throughout infancy. If your baby’s fussiness or gas seems excessive, ask your baby’s physician about switching.
Specialized nutrition baby formula
If your baby has a food allergy or other specific nutrition needs, specialized nutrition formulas can help meet their needs.
For cow’s milk allergy, your baby’s doctor might recommend Similac® Alimentum®. It’s a hypoallergenic, extensively hydrolyzed protein-based formula for infants with colic symptoms due to protein sensitivity and food allergies.

Similac® NeoSure® is specially designed for babies born prematurely to promote catch-up growth on the outside—and important development on the inside. It’s a nutrient-enriched formula that has increased protein, vitamins, and minerals compared to term infant formula.

Organic baby formula
Organic formulas contain the same ingredients you would find in a standard, milk-based, iron-fortified formula. The difference is that all certified USDA-organic products must meet the USDA’s strict production and labeling standards. Products with the USDA organic seal must contain at least 95% organic ingredients and have no genetically modified ingredients. Learn more about Similac® Organic.

As your baby grows into a toddler and you start introducing new foods, they may miss out on some important nutrients. Toddler formulas, like Go & Grow 360 Total Care® by Similac®, are designed for children between ages 12 and 36 months and can help fill nutrient gaps.
