Rated 5 out of 5 by No more tummy troubles! This formula has been a life saver with one of my twin boys! My boys are 5 months old and around 4 months one of them started having lots of gas and was crying a lot with a regular milk based formula. We discussed this with our pediatrician and he recommended this product. Since then my son is doing so much better. The only downside is the cost of this formula. With twins on formula the cost is overwhelming. I wish there were coupons or rebates to help us out! May 22, 2016

Rated 2 out of 5 by Made things worse My baby had frequent spit up on the similac sensitive and was always spitting up chunks. My ped recommended the soy and it made him even worse. He would throw up everything he just ate and it made him very constipated May 14, 2016
Rated 5 out of 5 by Wonderful!! This product has worked wonders for my daughter!! Galactosemia baby that can't have any milk or dairy, this product is literally a life saver. Her growth is off the charts, 96% for height and 93% for weight! Her specialist says she's the "picture of health" Thanks Similac! April 28, 2016
Rated 4 out of 5 by This is a good product but breast is excellent. I started breastfeeding from the beginning but ended up having to supplement. We tried Honest Co. organic, Similac organic and both left Baby with horrific constipation. Finally, we tried Soy Isomil in the ready-to-feed containers. Our only issue is the horrible smell of Baby's poo and gas. Her stool never had an odor until we put her on formula. However, we are grateful for the Similac Soy Isomil brand. Would you please consider providing organic soy formula soon? Thank you for the non-GMO samples we received this week. We won't use them because the Soy Isomil has been good for our baby's growth and development but we will certainly pass the samples on to a wonderful mom who will use them. April 27, 2016
Rated 2 out of 5 by Taste is good while testing some formulas to see which one is going to best for my baby girls tummy and this just made it worse, she was fussier and it seemed she was in pain trying to pass gas, when she did go it was thick and a dark green color (very dark), I probably should have gave it more then a week but after seeing her in pain i switch to similac organic April 18, 2016
