Understanding Reflux in Babies
Reflux (or GER—gastroesophageal reflux) happens when stomach contents come back up into the esophagus. Babies have weak esophageal sphincters, so some spit-up is normal. When it's frequent or causes discomfort, parents look for solutions—and formula choice can help.
There are two main approaches: thickened formulas (like Enfamil A.R. and Similac for Spit-Up) that reduce how much comes up, and gentle formulas (like Similac 360 Sensitive or Kendamil Goat) that are easier to digest and may reduce gas-related discomfort.
If your baby has both reflux and gas, a gentle formula may work better than an AR formula alone. See our Similac vs Enfamil comparison for more brand context. Many families use both strategies: small feeds, upright positioning, and the right formula.
AR (Anti-Reflux) Formulas Explained
Enfamil A.R. and Similac for Spit-Up are thickened formulas. They use rice starch (or similar) that thickens when mixed with stomach acid, so the formula sits lower in the stomach and is less likely to come back up.
How They Work
You mix the powder with water as usual. Once in the stomach, the starch absorbs fluid and swells, thickening the feed. Clinically, this reduces spit-up frequency and volume. They're safe from birth and widely recommended by pediatricians for significant regurgitation.
Nipple tip: Thickened formula flows slower. Use a cross-cut or level 2 nipple so baby doesn't have to work too hard. Standard slow-flow nipples can make feeding frustrating with AR formula.
Goat Milk: A Gentler Option
Kendamil Goat isn't thickened, but many parents report less reflux and fussiness. Goat milk has smaller fat globules and forms softer curds in the stomach, which can be easier for sensitive babies to digest.
It's a good choice when reflux seems tied to sensitivity rather than pure regurgitation volume. If your baby spits up a lot but also seems gassy or uncomfortable, goat milk formula is worth considering alongside or instead of an AR formula.
When to See Your Pediatrician
- Poor weight gain or failure to thrive
- Blood or bile in spit-up
- Difficulty breathing, wheezing, or choking during feeds
- Refusal to eat or severe irritability
- Reflux that doesn't improve by 12–18 months
Most reflux is normal and improves on its own. If you're worried, your pediatrician can rule out more serious issues and help you choose the right formula.
🏆 Final Verdict
Our Recommendation:
- 🏆 Best for spit-up: Enfamil A.R. (rice starch, clinically proven)
- 🏆 Best for reflux + gas: Similac 360 Sensitive or Kendamil Goat
- 🏆 Best organic option: Bobbie Organic Gentle
- 🏆 Best budget: Gerber Good Start SoothePro
Bottom line: If spit-up is the main issue, start with Enfamil A.R. If gas and fussiness dominate, try Similac 360 Sensitive or Kendamil Goat. Give any new formula 3–5 days before judging. For more options, see our complete baby formula guide.

❓ Frequently Asked Questions
Does thickened formula help reflux?
Yes. Thickened (anti-reflux) formulas use rice starch or other thickeners that expand in the stomach, making it harder for milk to come back up. Studies show they reduce spit-up frequency and volume in many babies. Enfamil A.R. and Similac for Spit-Up are the main thickened options.
What formula do pediatricians recommend for reflux?
Pediatricians typically recommend Enfamil A.R. or Similac for Spit-Up for significant spit-up. For reflux plus gas or fussiness, they may suggest Similac 360 Sensitive or Kendamil Goat. Always consult your pediatrician before switching, since some reflux needs medical management.
Is goat milk formula better for reflux?
Goat milk formula can help some babies with reflux because it has smaller fat globules and forms softer curds in the stomach—easier to digest than cow's milk for some infants. Kendamil Goat is a top pick. It's not a thickened formula, so it won't reduce spit-up the same way as Enfamil A.R.
When do babies outgrow reflux?
Most babies outgrow reflux by 12–18 months as their esophageal sphincter matures and they sit upright more. Spit-up often peaks around 4 months and improves by 6–7 months. If reflux persists past 12 months or causes poor weight gain, see your pediatrician.
Can switching formula help reflux?
Yes. Switching to a thickened formula (Enfamil A.R., Similac for Spit-Up) can reduce spit-up. Switching to a gentler formula (Similac 360 Sensitive, Kendamil Goat) may help if reflux is tied to gas or sensitivity. Give any new formula 3–5 days before judging results.
Is Enfamil AR safe for newborns?
Yes. Enfamil A.R. is designed for infants from birth through 12 months. The rice starch thickener is FDA-approved and clinically shown to reduce spit-up. Use the correct nipple size (often a cross-cut or level 2) since thickened formula flows slower. Consult your pediatrician before switching a newborn.
