How Each Formula Can Help Babies

The Enfamil AR and the Enfamil Gentlease are both formulated to ease stomach issues in babies and contain nutrients to ensure proper brain and immunity development in infants. You can select one based on the specific needs of your baby. However, neither formula can be fed to premature babies for not being sterile.

  • Enfamil AR

As mentioned before, the Enfamil AR has added rice starch and is specifically designed to reduce spit-ups by babies. But there’s more. 

The product is made following acid reflux prevention guidelines provided by the American Academy of Pediatrics and contains DHA as well as probiotics. It is a trusted brand and recommended by pediatricians worldwide.

The Enfamil AR is a better solution compared to mixing rice cereals with milk. Mixed rice cereals don’t supply the necessary nutrients your baby needs and just provide empty calories. The Enfamil AR is also easier to feed using a bottle instead of rice cereal mixes. 

This formula is gentle enough to feed infants under 12 months of age.

  • Enfamil Gentlease

Gentlease is formulated for babies sensitive stomachs who find it hard to digest regular formulas. It is designed with milk-based proteins that are slightly hydrolyzed for better digestion. 

Infants who suffer from digestion problems get gassy and irritated after feeding. Frequent spit-ups, diarrhea and upset stomach are symptoms of digestion problems. The Enfamil Gentlease provides comfort from these problems within 24hrs of feeding. 

The Gentlease has a taste and formula similar to breast milk and can be used as a substitute for that. Because of the similarity in taste, it is easier for babies to transition from breast milk to formula.

The texture of Gentlease is thinner than AR and can be fed easily with a bottle. You can choose the liquid ready-to-feed version if you don’t feel like mixing them every time before feeding.

The Negative Aspects / Cons of Each Formula

  • Enfamil AR

AR has some negative side effects that can be seen in some babies. The formula thickens in the stomach. This can sometimes cause constipation in your baby. Also, it can be tough to feed through a nipple due to its thick consistency. 

To prepare a bottle of Enfamil AR, you need to shake vigorously to properly mix the thick formula. This traps air bubbles inside that can make the baby gassy and unsettled.  A recommended 5 minute waiting period can be annoying.

You must wait for some time after mixing the AR to let the air bubbles escape and make your baby burp after feeding. 

Your baby may get common rashes after switching to or changing formulas. It is normal and should subside when the baby becomes accustomed to the new formula.

  • Enfamil Gentlease

The formula works differently for each baby. The Enfamil Gentlease has a strong smell, which some babies may not like. The formula can also create irregular bowel movements in some. 

If you are buying these online, then be careful about the seal. The cans can get heavily damaged, and you should not use an open can no matter what. Contact the seller and immediately discard the formula.

Some reviewers also reported missing a scoop or lid when ordered online. 

The powder version doesn’t work as promised for some but you can try the liquid ready-to-use one in that case.

How to Prepare Each Formula

You should be careful while handling baby formula because one little mistake can seriously harm your baby’s health. 

  • The formula should be kept in a cool, airy place with the lid on. You should not use open or expired products
  • Wash your hands properly before starting
  • Make sure the bottle, ring, nipple, and cap are all clean. You can boil them in water after each use to keep them sterile
  • You can ask a pediatrician about the kind of water you should use. Some pediatricians advise using boiled water to prepare the bottle
  • Fill up the bottle with water and make sure it’s not warm. Warm formula spoils quickly. Refrigerate or feed the baby immediately if you’re using warm water
  • Scoop the required amount of formula into the bottle and shake well to mix. Check the taste and temperature (which should be neutral) on your wrist before feeding the baby 

Final Verdict

The Enfamil AR and the Enfamil Gentlease are both great formulas to feed your baby. Every formula reacts differently for every infant.

What may work for others, may not work for your kid. The Enfamil AR and the Enfamil Gentlease are both pediatrician approved. These also have great reviews.

So, if you’re having trouble with other formulas, make sure to give these two a try. Consult with your pediatrician and if one does not work after a trial run, do not be afraid to try the other.

My personal experience, while just a small sample, is that Enfamil AR parents are extremely loyal and find that product works for their babies.

Ready To Use Example:


  1. How Can I Ensure My Baby Doesn’t Burp Out the Formula?

Make sure to always burp your baby while feeding to reduce acid reflux. Using a formula such as Enfamil AR that promises to reduce spit-ups can also help. 

The Enfamil AR contains rice starch that thickens inside your baby’s stomach to prevent burping out. It is more reliable than mixing rice cereal into the formula.

  1. Can I Microwave Baby Formula?

No. You should never microwave baby formula. Baby formula spoils very fast. You should immediately feed it to the baby after preparing or refrigerating it at 35°-40°F. Never freeze the formula. Let it come to room temperature before feeding. Do not use the formula that has been outside the refrigerator for two hours and finish feeding within an hour of starting or discard otherwise. Always read the label before preparing.
