Rated 5 out of 5 by from We love Similac! We started our new baby girl on Similac Advance but she was fussy and crying all the time, so we switched to Similac Soy Isomil and it was a godsend. She has been a completely different baby since we switched. She is such a happy baby & I am so thankful for Similac.

Rated 5 out of 5 by from I love it. When i had my son i strictly wanted to breast feed but after a while i started noticing that he would puke everything up with in minutes of being done eating or he would be so constipated he would scream in pain. No matter what i did to my diet nothing worked. Well our doctor found out he was lactose intolerant and allergic to my breast milk so the recommended that we try soy. Ever since i started him on soy formula he has been able to eat more and go better. Just wish i could by bulk in the similac formula he goes through a can of the powder ever 3 days and goes through the premade bottles every day . He eats so much of it.
