Similac Organic Reviews

Rated 5 out of 5 by from Great product. My youngest is developing nicely. When my wife stopped breastfeeding my youngest at his 5-month mark we immediately put him on the Similac organic optigro instant formula. We were very pleased that he took to it immediately. We had no issues with gas or irregular bowel movements. My little guy is now 9 months old and has been making steady and healthy gains in size and weight as well as cognitive development. The misses and I feel blessed as he is one happy baby. If we decide to have another child I would definitely use this product without hesitation.

Rated 1 out of 5 by from Terrible for my baby girl I was excited when I saw Similac had made an organic formula. I purchased the ready to feed kind for my 1 month old and that was the worst thing I could’ve done. She had so much gas pain, couldn’t poop and when she did it was so hard and made her cry, and the worst thing that happened; this formula made her saliva thick which caused her to choke on her saliva in the middle of the night! She couldn’t seem to swallow, so my husband had to flip her upside down and pat her on the back to get it to come out. Worst scare of my life! We immediately switched to Alimentum, and she has been doing MUCH better. She’s 4 months now.

Rated 1 out of 5 by from Disappointed Mom I was excited when I saw Similac had an organic formula now, as it didn’t exist with my first born. The excitement was short lived. I switched from the supplementation (which I loved) to the organic after I decided to stop breastfeeding. The organic leaves a thick residue and foams which gives my LO gas and makes her fussy. I am really upset I didn’t just go with the proadvance like my with my first. I bought the largest size which was a waste of $30, because I am going to purchase the proadvance and toss the organic. I should of read the reviews first before purchasing, but having used other Similac products I had faith in the brand and felt no need to. I wouldn’t recommend this product to anyone.

Rated 5 out of 5 by from Wonderful! Coming from a mom whose child has severe acid reflux, we have to use cereal in every bottle. We was put on gerber gentle and it was horrible. My baby puked 24/7. My doctor switched us to pro advanced and it was great. No puking but would cause belly aches sometimes. We then switched to organic & it is wonderful! All powder formulas are foamy that is why you stir and don’t shake. As for the “gritty” we use cereal in every bottle and that makes it kinda cakey so it honestly wouldn’t make a difference. But we have a healthy baby, who loves his formula, no puking, rarely a spit up, no belly aches or anything! All babies are different and you just have to find what works for them. Organic has worked wonders for my little one! Forever a similac mom!

Rated 3 out of 5 by from Foamy and leaves a thick residue I absolutely love Similac products. My LO started out exclusively breastfed, but I would supplement with Similac supplementation (which is absolutely amazing). When my breastmill began to dwindle I kept him on Similac Supplementation for another month. Yesterday I wanted to switch to pro advance, but when I aw there was an organic Similac I thought “this would be better”. Needless to say my son does drink it., but the thick residue as well as foam leaves me worried and upset I wasted money on this product thinking I was gonvong him the very “best”. I’ll be switching to pro advance, just wish I would have read the reviews first.

Rated 2 out of 5 by from Not what I expected! I wanted to love this formula! I try to give my son all organic! This formula stays powdery even after shaking for a long time. It gave my child such bad gas and he just stoooer eating... I just switched the formula again. I will see what happens. Starting to think about switching to emfamil since I’ve switched his formula 3 different times already...

Rated 1 out of 5 by from Really hoped for better I have been a similac mom since my first born. Now with our new baby boy I was feeding him organic ready feed formula which was great. It agreed with him right away, no discomfort or disruption in digestion and I felt good about giving him organic. So naturally when it came time to switch to powder I wanted to stick with the organic thinking it would not be an issue. It is SO gritty and thick it looked like he was going to vomit a few times. He hated every bit of it so much that he wouldnt drink, yet continued to hysterically cry out of hunger. I had to do an emergency run to cvs and get the regular pro-advance. I just bought that 30.8oz from BJs wholesale too so it's a huge waste of money. I cant donate it to anyone, only made 2 bottles with it. ** on a side note I did mix according to the directions, like I said I've been a similac mom from the get go. I'm not sure what's so different between the ready feed organic and the powder/water combo but it does not work for us .

Rated 1 out of 5 by from Baby too gassy and very fussy I was so excited to find that Similac had an organic formula. I used Similac for my first two babies with no problems. I bought this one for my newborn as a substitute for low breast milk and noticed she hates it. She spits up a lot, gives her gas, she can’t sleep after I feed her and it makes her poop after every feeding. The worst part is similar to everyone thick, foaming and leaves a lot of residue in the bottle. I’m sorry to give such a negative review but I just assumed that an organic product shouldn’t make a newborn feel this way.
