Not All Formulas Are Created Equal…🍼
There are five main categories of baby formula, though within each group there are lots of different brands and variations. Here’s a simple breakdown to help you understand the options:
1. Standard Infant Formulas
These are the most common formulas and work well for most babies who are growing normally without tummy issues. Examples include Similac Advance, Enfamil NeuroPro, Kendamil Infant, and Similac 360 Total Care. They provide complete nutrition for everyday growth and development.
2. Sensitive or “Gentle” Formulas
These are often marketed for gassy or fussy babies who may have trouble with lactose. They’re usually partially broken down and have less lactose (sometimes replaced with corn syrup solids or corn maltodextrin). Examples include Enfamil Gentlease, Ge**er Soothe, Similac Sensitive, and Similac Total Comfort.
3. Hypoallergenic Formulas
Think of these as “partially digested.” The proteins are broken down into much smaller pieces, making them easier for sensitive tummies to handle. They’re often used for babies with milk protein intolerance, allergies, colic, or more severe lactose issues. Examples include Ge**er Extensive HA, Alimentum, and Nutramigen. These are considered specialty formulas, can be very pricey, and may or may not be covered by WIC—so always talk with your pediatrician before starting one.
4. Amino Acid–Based Formulas
These are the most broken-down formulas—already in their simplest form. Because of that, they’re the easiest to digest. They’re usually used in more extreme cases like severe milk protein allergy, FPIES (Food Protein–Induced Enterocolitis Syndrome), or other absorption problems. Even though they’re very specialized, they still give babies all the nutrition they need.
5. Reflux Formulas
A common option here is Enfamil AR, which has added rice starch to thicken it. This helps formula stay in the stomach instead of coming back up, which is especially helpful for “mechanical reflux” (spit-ups from positioning or immature digestion in the early months). Sometimes, pediatricians may recommend adding rice cereal to standard formula for the same effect—but always under their guidance. Keep in mind that thickeners can sometimes cause constipation.
Alternative Protein Formulas
There are also soy- and goat milk–based formulas, which can be good options for babies who can’t tolerate cow’s milk protein. Just make sure they’re iron-fortified so your baby gets what they need for healthy growth.
—A Note on Switching Formulas—
If you’re trying a new formula, give it at least a week before switching again. Babies’ bellies need time to adjust, and it can take several days for irritation to settle down before you notice improvement.
