Rated 5 out of 5 by A thousand stars yes! I should really get hired by similac for how many times I've recommend similac soy! My daughter had awful colic we had tried every enfamil product out there including HA formulas. Nothing helped my poor baby! At 5 months I figured If I tried similac it couldnt be worse than what my baby was already feeling. I went out bought a tub of similac soy within 48hrs I could see the difference in her! Never had any constipation issues with this either, she goes 2-3 times a day. I absolutely love this product and tell everyone I can about it! Thanks for saving me Similac June 29, 2016
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
