How to Choose Infant Formula for Your Baby

Feeding your newborn is one of the most important decisions you will make as a parent. Whether you are choosing to formula-feed from the start, supplement breast milk, or transitioning from nursing — selecting the right infant formula can feel overwhelming. 

With so many brands and types on the shelf, how do you know what is right for your baby? 

Here is a clear, comforting guide to help you make an informed and confident choice. 

 

Understanding the Types of Infant Formula 

Most formulas are designed to mimic the nutritional profile of breast milk and are regulated for safety and nutrition. Here are the main types available: 

1. Cow’s Milk-Based Formula

• • Most used. 

• • Proteins are modified to make it easier to digest. 

• • Suitable for most healthy, full-term babies. 

2. Soy-Based Formula

• • Made from soy protein instead of cow milk. 

• • Lactose-free. 

• • May be an option for babies with galactosemia or dairy intolerance, but not ideal for babies with cow’s milk protein allergy. 

3. Hydrolyzed (Hypoallergenic) Formula

• • Proteins are broken down into smaller pieces to reduce allergic reactions. 

• • Used for babies diagnosed with cow milk protein allergy or digestive disorders. 

• • More expensive, often prescribed or recommended by pediatricians. 

4. Lactose-Free Formula

• • Made for babies with lactose intolerance (rare in infants). 

• • Replace lactose with other sugars like corn syrup solids. 

5. Specialized Formulas

• • For preterm infants, those with reflux, metabolic disorders, or other medical needs. 

• • Must be recommended by your child’s doctor. 

 

Key Nutrients to Look For 

While all formulas sold are nutritionally complete, some ingredients support specific areas of development: 

• Iron – Prevents anemia and supports brain development. 

• DHA & ARA – Omega-3 and Omega-6 fatty acids for brain and eye development. 

• Prebiotics & Probiotics – Support digestive and immune health. 

• No Added Sugar – Avoid formulas with added sucrose or corn syrup as a primary ingredient. 

 

How to Choose the Right One for Your Baby 

Here is what to consider when narrowing down your choice: 

✔ Baby’s Health and Needs 

• Digestive sensitivities? 

• Allergies or family history of food allergies? 

• Premature birth or special medical needs? 

✔ Family Preferences 

• Vegan/vegetarian diets (may prefer soy-based). 

• Organic vs. non-organic options. 

• Convenience (powder vs. ready-to-feed). 

✔ Budget and Availability 

• Choose something consistently available in your local store or online. 

• Store-brand formulas are often just as effective as name brands — and more affordable. 

✔ Ease of Use 

• Powdered: Most economical, must be mixed with water. 

• Liquid concentrate: Mix with equal parts water, less messy than powder. 

• Ready-to-feed: Easiest, no mixing needed — great for newborns or night feeds. 

 

 When to Call the Pediatrician 

Always consult your baby’s doctor if: 

• Your baby shows signs of intolerance: rash, vomiting, diarrhea, constipation, excessive crying. 

• You are unsure which formula to choose. 

• You are considering switching types or brands. 

• Your baby is not gaining weight or feeding well. 

Your pediatrician can help guide you toward a formula tailored to your baby’s specific needs. 

 

Choosing infant formula can feel like a big decision but remember — there’s no one-size-fits-all answer. Every baby is different, and what works for one may not work for another.  

 

Book a telemedicine appointment if you have questions when your pediatrician’s office is closed.
