Enfamil A.R. also uses rice starch for its thick consistency. Nonfat milk is added for protein, and a mix of vegetable oils are used as a fat source. Enfamil AR contains Natural Defense Dual Prebiotics.

Unpleasant taste and smells could have a negative impact on both the parents and infants experience with either formula.

Reviewers of Similac Spit Up have reported it to have a pleasing taste and smell. Due to its higher sugar content, the taste is extremely palatable for your infant. 

While reviewers have not reported any displeasing smell of Enfamil AR, its taste is however slightly more bitter when compared to that of Similac Spit Up. This is due to its more nutrient focused formula that sacrifices some flavor for higher nutritional benefits. 

While the difference in smell and taste between Similac and Enfamil is by no means staggering, sometimes even the most subtle difference can become a deciding factor for you and your baby.    


In most cases, Enfamil AR tends to be a tad pricier than Similac Spit Up. However being that the ultimate goal is picking a formula that is the most effective in assisting with your infant’s digestion, this can be somewhat of a non-issue if Enfamil AR is your preferred choice.

Prices can vary and range based on which variety you choose.  Check the selection of each formula on amazon to find the best value.

If you are looking to save in cost then purchasing the powdered version over the other varieties for both formulas is the best solution.

Premade formulas, while convenient will always be a pricier option. It is worth noting however that the premade formulas tend to be smoother. That results in less clogging and overall superior feeding experience.

The premade bottles also save you some extra work in terms of cleaning. So it all depends on whether or not you find enough personal value in some of these luxuries.

Enfamil AR pouches are also more expensive than the canned powder versions.

Additionally, the premade bottles contain a smoother consistency when compared to that of the powdered version. For parents with picky babies, this can ultimately be a deciding factor.

Enfamil AR  comes in an even larger variety with premade bottles, powder, and individually wrapped serving pouches for pouring your own bottle on the go.

These individual pouches are a big plus as they can take a lot of the tricky guesswork out of the equation when trying to coordinate and plan the amount of formula to prepare for trips outside of the home.
