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!

Rated 4 out of 5 by from Third similac formula We have tried three formulas, this being the fourth! The first two were similac advance then sensitive! He done horrible on both of these, then we switched to enfamil AR, he done okay on it, and now our doctor recommended this to us so I pray that it works!

Rated 3 out of 5 by from Formula #3 This was the 3rd formula we tried. After Sensitive, we thought soy would help, but she reacted the same to this formula as the Sensitive; she was still in pain with lots of gas and constipation.

Rated 5 out of 5 by from Healthy baby My little one had a very sensitive tummy and couldn't even handle breast milk. We started her on the similac soy and she has done great ! No issues and she is happy and healthy.

Rated 1 out of 5 by from So constipated My baby was on this for aboutique a week and a half and got so horribly constipated. Awful, hard poo that hurt him to pass (you knew when he was going cause he would cry). He has a milk protein allergy so we thought this would be good, but nope. Don't know if he also has a soy allergy, but 10 days was long enough and I wasn't gonna try it any longer!

Rated 5 out of 5 by from So Far So Good This product has helped my son sooo much! We have been on Similac Sensitive, Spit-Up, & Alimentum all told by our doctor to try. Nothing was working. Finally, went out on a limb and tried Similac Soy- all I can say is "MIRACLE WORKER!". He doesn't fuss as much as he used too, if at all. He is taking longer naps, now that he is actually sleeping longer then 30 minutes. And sleeps all night long. He is getting the sleep he needs & so are we. If you have a fussy, restless infant, this product is a MUST TRY! Happy Baby!- Happy Parents!- Happy Home! Thank you!

Rated 5 out of 5 by from Love the product! This formula has changed our lives! The first two months was a guessing game as far as vomit, rash, fussiness, and diarrhea! Two weeks after starting this he completely cleared up and we started enjoying our time with our new baby! Happy baby = more sleep for mom = happier home! Way to go Similac Soy!
