Similac Alimentum Reviews

Rated 5 out of 5 by from Wow, what a difference a day makes! I decided to try this formula as my son was still having painful gas and discomfort with the sensitive formula. I was using gas drops in every bottle. With the alimentum he is doing great! Belly bloat and painful gas are gone. He is also now having regular bowel movements. Trust your instincts if you think there is a sensitivity.

Rated 1 out of 5 by from Awful... my newborn stopped eating After using Similac Pro as recommended from the hospital, my one week old newborn developed chronic gas pain, fussiness, non-stop flatulence, and did not sleep. After doing as much research as I could, I switched him to this one. The smell is AWFUL, the taste is AWFUL and after 4 days of my newborn eating this, he has decided to stop eating. His gas has continued and has in fact worsened. This formula is so thin, so when he was eating, he was eating every 1.5-2 hours when before he was eating every 3 hours.

Rated 4 out of 5 by from Good Product, Questionable Service My 1 month old became a gummy smiling baby overnight after switching to the ready to feed formula. Saved both of us. However, it is very expensive and we have been advised by our pediatrician not to use the cheaper, powder version at this age. We contacted Similac for coupons to assist with the cost and they were extremely responsive - HOWEVER they mailed us two huge packages of all their other types of formula and only one can of the powdered Alimentum. Feels like they are wasting their money and resources on those packages. Certainly was a let down for us when we received it. Appreciate the thought I suppose.

Rated 3 out of 5 by from I also hate the can! Put it in the regular plastic similac tub with a hinge! And make it available in a larger size! I feel like I’m buying formula alllll the time.

Rated 1 out of 5 by from The liquid and Powder are not the same!!! Very disappointed! I always used the ready to feed since my LO was 1mo old . LO doctor told us to change milk said first it is very costly and LO has gotten better with her colic. I wanted to do the changes slowly so I decided to just get the powder, I was very disappointed, Wasted my money & how in the world same brand and name but has different ingredients! As soon as I gave it to my LO she started throwing up!

Rated 5 out of 5 by from This is a god send BUT it’s soooo expensive! My son had a 360 degree difference within a day on the ready to feed formula but the issue is the price. The powder version did not sit well with my baby but the rtf is great! Not to mention the awful smell the powder one has

Rated 5 out of 5 by from Highly recommend for babies with food sensitivities We have used this formula for both my daughters. I highly recommend for food sensitive babies. Also, I contacted Similac and they sent me free samples and coupons. Great company and great product. Only complaint has nothing to do with the product. It's just not clear how to earn points toward more free samples as I use coupons and purchase similac all the time yet still have 0 points.

Rated 2 out of 5 by from The ingredients are an issue When my child was born I was a breastfed advocate, but I had too little milk to give her. So I started her out on Gerber but she was breaking out so her doctor suggested Alimentum. The powder form was just awful it smelled bad and my baby did not like it so we switch to the rtf. Boy, what a difference, she takes it with some ease. My only issues with rtf is the price and how sweet the stuff is. Seems like a lot of sugar...
