Frequently Asked Questions

1. Do soy formulas taste different from milk-based formulas?

Yes, soy formula tastes different as its flavor is determined by the base, minerals, vitamins, and sweetener utilized.

2. Will soy formula cause constipation in my baby?

Some soy and cow milk-based formulas generate firmer bowel movements. However, formulas with partially or completely hydrolyzed milk proteins (often known as “hypoallergenic” formulas), which may be suggested for infants with a cow’s milk allergy or sensitivity, may cause loose bowel movements.

3. Can I use soy formula for a preemie?

Pediatricians do not recommend soy formula for preemies, as it might cause reduced bone mineralization in them.

4. Is soy formula good for babies?

Doctors recommend soy formula if parents do not want babies to ingest animal-based protein or if their baby is lactose-intolerant (1). However, some infants may be sensitive to estrogen-like compounds in soy (2). Speak to your doctor before giving soy formula to your baby.

5. Does soy milk make babies poop more?

Yes, to some extent. Infants who consume soy formula have increased bowel movements than infants who drink cow milk.

6. How do you know if the formula isn’t agreeing with the baby?

Whether it is a plant-based formula or cow milk-based formula, your infant would show some signs if they are formula intolerant. Vomit, diarrhea, and fussiness are some common symptoms (1).

7. Will soy formula help with reflux?

Do not offer any soy formula to your baby if they have reflux. Speak to a pediatrician, and they would recommend anti-reflux formulas for your baby (3).

Soy formulas are great alternatives to cow’s milk-based formulas if your child is lactose intolerant or your family is strictly vegetarian. They are made with natural ingredients and are free of added colors or flavors, and they help meet your child’s nutritional needs and are easy on your little one’s gut. When looking for the right soy formula for your baby, ensure it comprises nutrients that promote your child’s growth. Also, check with a pediatrician before adding soy formula or any new dietary supplement to your baby’s diet.
