Rated 5 out of 5 by The best Best milk ever for my pre girl She didn't wanna eat and with this product she have done so much better. Recommended 100% June 27, 2016
Rated 4 out of 5 by Great but needs more options The product is wonderful and my lo has increased feeding since switching. I wish it came in multiple sizes. I see the extra large canisters (2.18 lbs.) for the other formula types. Not to mention the ready made, I can only find the 1qt and that is hard to keep cool, once open, when traveling long distance. I used to buy direct from Abbott for 2oz ready made 48 in a case which are great for travel. Occasionally I find the 8 oz. six-pack but not usually near my home. June 27, 2016
Rated 5 out of 5 by only formula that helped my son! amazing! My son was originally breast fed and I ended up switching him to enfamil because that is what wic covers for me. I tried him on milk based and found out his stomach couldn't tolerate it so we switched to gentlease. No relief and extreme constipation. I switched to prosobee and he was still constipated. The only formula that my son is able to go to the bathroom with and not have gas is this product. Unfortunately wic won't cover it but I would rather buy out of pocket because the product is well worth it. My son is doing amazing on it. June 23, 2016
Rated 4 out of 5 by Good for our little one Our daughter has a cow's milk allergy and soy formula is the only one she is able to tolerate. We tried the sensitivity one but because it's still a milk-base this was our only option for her needs. June 20, 2016
Rated 2 out of 5 by Bad taste bad gas My baby was very fussy on the Similar advance at first so we tried this, it gave her bad bellyaches, stinky gas and constant crying. The total comfort is a little better but I think it's the added sugar instead of corn syrup because my baby has done great on Gentleness from enfamil. I've purchased the advance, total comfort and soy and haven't received any samples or coupons to help me try any others....enfamil has sent numerous samples and coupons, that's how we ended up using gentleness.

Rated 1 out of 5 by Didn't help! Went from Similac Advance to Similac Soy and my baby just got worst. She started off constipated with the Similac Advance. So I switched her to the Similac Soy and now she's having watery stool, she's very gasy, and is spitting up!!! And she is very fussy, this just made things worst for my baby!! June 14, 2016
Rated 5 out of 5 by Only formula helped baby with acid reflux! We went through breastfeeding and many formulas. Similac Soy is the only formula that my 2 1/2 month old baby was able to tolerate with having acid reflux and spitting up. We are now five months old, continuing using Similac Soy, healthy, happy and active baby. This product is wonderful! June 8, 2016
Rated 5 out of 5 by Baby allergy My son was getting really fussy and got a rash/eczema all over his face and head. Doctor said he is allergic to milk (formula) and put him on soy. He is doing so much better and we are so thankful. Only downfall is cost, we will only use similac, no generic, but it's definitely worth it for our child! June 2, 2016
