How They Help Babies Stop Spitting Up?

Infants under 12 months can suffer from spit-ups due to many reasons. The upper stomach lining in infants takes time to develop. Meanwhile, the babies have trouble digesting and keeping the food down. In addition, since infants are always laid down on their backs, reflux is more common in them.  Not much is more annoying than a baby with constant vomit coming out of them, but I felt so bad and would do whatever I could to help.

Enfamil AR and the Similac Spit Up both are rice starch-based milk formulas that reduce spit-ups in babies. How each formula helps babies are given below;

  • Enfamil AR

Enfamil AR claims to reduce spit-ups in babies by 50% within the first week of initiation. The rice starch thickens as soon as it’s consumed and makes it hard for the stomach to push it up. 

Enfamil AR contains Prebiotics that help safeguard a baby’s guts and develop immunity by allowing the growth of good bacteria. 

It has DHA and Choline, which promote better brain development in babies. It has lactose and fortified iron to ensure that your baby gets all the necessary nutrients.

This formula proved in a clinical trial that infants fed Enfamil AR have less frequent spit-ups compared to when they were not.

Enfamil AR follows the guidelines of the American Academy of Pediatrics (AAP) on reflux control while making the formula.

  • Similac Spit Up

Similac Spit Up is nutritionally balanced to ensure that your baby sees proper growth. It supplies 20 calories per fluid ounce with nutrients like DHA, Vitamin E, and Lutein. 

The blend of DHA, Vit E, and Lutein in their formula enables better brain, sight, and cell development.

Similac Spit Up contains nucleotides, prebiotics, and carotenoids that help build good immunity and digestion in babies.

The added nutrients are proven clinically to support growth in babies. It also contains a lower amount of lactose for easy digestion. Furthermore, it is kosher, halal, and gluten-free.

Preparation of Rice-Based Formulas

Rice-based formulas are thicker and may have slightly different preparation steps. You should read the instructions on the can to prepare the formula correctly. Enfamil AR requires a 5 minute wait time, but to tell you the truth when the baby is crying we have used almost instantly with no side effects. But waiting does allow it to thicken a bit more.

Steps to Follow

  • Wash your hands properly before opening the can. Clean around the can where you’d be working as well. Be sure to check the CDC guidelines.
  • Use the scoop provided with the can to take out the powder. Keep the scoop inside the can and make sure that it’s dry.
  • Ask your pediatrician about the kind of water you should use.
  • Make sure the bottle, nipple, ring, and cap are clean and sanitized.
  • Use the exact measurements given on the can or recommended by your pediatrician while preparing the formula.
  • Since rice formulas are thicker, you need to shake these longer than your usual formulas to mix.
  • Wait around 10 mins after mixing to let the air bubbles get out before feeding your baby. This will reduce the amount of gas they get.
  • Make sure to burp your baby frequently while feeding. My babies were always asleep so fast it was harder to burp.

Which One Is It?

Similac Spit Up, and Enfamil AR are both good formulas for babies with acid reflux and spit-up problems. My friends that have newborns have good things to say about both.

The Enfamil AR is widely recommended by pediatricians, and the Similac Spit Up is more popular among consumers.

Both formulas are nutritionally balanced and can ensure the proper development of your little one. Similac Spit Up uses more sugars, so the taste is more enjoyed by babies.  

Enfamil AR costs more than Similac Spit Up, but it has more options. You can use the powder or liquid one. It also has small packets that can be easily prepared while traveling. The liquid one is more smooth and can be used without the hassle of preparation. 

Despite the pros and cons, both formulas are good for babies. You can check out samples first to see if a brand works out for your baby.  Always follow the advice of a pediatrician.
