Similac pro advance Positive Reviews  

“My daughter did very well with the pro-advanced formula. She is 6 months now and she very rarely (less than 10 times) spit up. Rarely had a hard time sleeping from gas in the first 3 months.”  

 – Reviewer on Similac’s website.  

“With twin babies we went through a couple different formulas trying to find one that would work well for both of them (vs having to do two different kinds of formula). We had one baby who had bad reflux and was always spitting up and crying like he was uncomfortable. Our other baby would cry and always had gas issues.. finally we gave this one a try and I’m so glad we did! Both babies started acting so much better gas/fussiness wise and very little spit up issues since starting! After reading a bit into formulas this one isn’t horrible either with its ingredients and added probiotics (we still give another probiotic on top of whatever is in this formula) So far this keeps my now 6mo old babies healthy and happy, so we are sticking with it even though it’s a bit more spendy (especially with twins), I think the ease on my babies tummies is worth it!”

Additional review

“I can’t even begin to count all of the formula’s we tried for my 4 month old. Every brand, every type. I was heartbroken to not be able to breastfeed, so finding the perfect formula was so important to me. I started with the organic, which made him spit up. Tried most other brands, which hurt his tummy and caused constipation, which led me to try the sensitive tummy versions, which were also a no go. Then we tried pro advance… and it was literally life changing. No more spit up, happy tummy, and he was finally sleeping. 1000% recommend!”

Negative Reviews about Similac pro advance sensitive  

“My son was in the NICU for the first two weeks of his life. He was given Similac Pro Advance, but the ready made formula. Despite having a serious infection, my baby gained a full pound the first week of his life and has never looked back, lol. I bought the powder version to go home with. Over the span of 8 months, I have tried different formulas but always come back to Similac and now will just stick with it until he is off formula. 0-4 months he seemed to spit up a lot so I tried different formulas, including the spit up formula by Similac and the sensitive formula; I didn’t notice a difference though with the sensitive formula he seemed to spit up a bit more. I think it was just his age because he has seemed to grow out of the excessive spit up.”

“I’m a first-time mom and was not making enough milk in the beginning. I opted for this because it’s advertised as the closest formula to breastmilk. I bought a can and it was fine but on our second can our baby started getting fussy and crying for long periods of time, she hardly slept. Our baby threw up constantly and had a lot of gas. She had all symptoms of reflux, after a couple of sleepless nights my milk came in and I decided to exclusively breastfeed. It was a huge difference, she slept more and was no longer throwing up gas went away too. Then all of a sudden I ran out of milk (My supply went down) and I decided since all I had was the can of formula I’d try again. Symptoms came back the same day of feeding and she was very fussy I felt like a terrible mom. I would love to give Similac another chance but I would hate to spend another 35 dollars on a can we won’t use.”
