Rated 5 out of 5 by from Worked like a charm! After trying numerous other brands I found that this one worked the best for my daughter. She had really bad acid reflux and since I switched her to this formula I have not had any further issues. This formula is a lot easier for my daughter to digest. I highly recommend this product to all moms! The only problem I have encountered is stores in my area do not carry this type in the travel size bottles.

Rated 5 out of 5 by from Works Wonders After trying many different formulas, Similac Soy has helped so much with our little one! She is no longer fussy due to gassiness and being lactose, I highly recommend this formula to anyone that has a baby with a sensitive stomach!!

Rated 5 out of 5 by from Best choice for both of my babies! This was the best formula for both of my babies! Both of them had sensitive stomach, very gassy. This was the 3rd Similac Formula they tried and worked wonders for both of them! Any baby that seems fussy and gassy, I would recommend this, it may be that your baby cant handle a milk based formula!

Rated 4 out of 5 by from similac soy isomil tummy care vs #1 fed in hospital This product has definitely helped my baby from past 7 months but we faced some trouble in recent times. It is because there are 2 FLAVORS of similac soy iosmil. 1) similac soy isomil TUMMY CARE - good for my baby 2) similac soy isomil #1 FED IN HOSPITAL - very bad It took 10 days to figure out this difference. I hope this review will help few other moms. My question to similac is "what is difference between those 2 flavors?"

Rated 1 out of 5 by from Did not work for our 4-month old This formula did not work for our 4-month old as he would throw it all up about an hour after he ate it. We tried a few different times as we need to supplement with formula. Thus, I cannot recommend it because our son just throws it all up, which is very concerning!

Rated 5 out of 5 by from Pediatrician Our Pediatrician recommended switching to a soy based formula due to our one month old having severe constipation on milk based formula. After a week long transition she is now having regular bowel movements and a very happy baby! The pediatrician gave us a sample can of the Similac Isomil and because it worked so well it is now what we buy!
