Rated 5 out of 5 by from Great for my daughter. I feel confident that she is getting good nutrition. This formula is great for my daughter. I feel she is getting a quality nutrition. She doesn't spit up much and she's growing good. I'm very happy.

Rated 1 out of 5 by from Made my 4 month old severly constipated. Would not purchase again. Switched my 4 month old to this formula because of the organic ingredients but unfortunately it made him severely constipated to the point that we had to see his pediatrician. Poor baby turned bright red and cried uncontrollably, I also had to use suppositories to help him express the bowel he had stuck. Not a great experience and I will not be purchasing this product anymore. Pediatrician recommended to switch to Alimentum and so far baby likes it and has not had any issues with constipation.

Rated 2 out of 5 by from Very thick, doesn't mix My son has been primarily breast fed until 4 months when my milk dried up, and I wanted only the best formula for him. I appreciated the fact that Similac made an organic formula, so I bought it. He doesn't have energy bursts from it, nor constipation, however the formula doesn't mix. It stays very grainy and by the time he drinks the milk, a VERY thick residue is left in the bottle, or even a TON of foam (and I don't shake the bottles, I stir them) Formula shouldn't do that...

Rated 1 out of 5 by from Awful Formula Our first child is currently five months old. I breastfed our daughter for the first 4 1/2 months, but we would use Similac's Supplemental formula because some days she would eat more than I was producing. She seemed to like it; there were no digestive issues, other than occasional gas (which I think is normal). When I stopped breastfeeding, we decided to go with Similac's Organic formula because we thought "Organic = good for you." Nope - not for our daughter. After about a week, I realized that she wasn't finishing her bottles, she would sometimes crunch her stomach while eating and cry, and her stools were different. I later learned these were signs of constipation. We also noticed that after her last bottle of the day (she would normally go to sleep after eating), she would instead roll around in her crib and stay awake much later than normal. She would eventually fall asleep on her tummy (another unusual sign because we put her in her crib on her back, and she would normally stay that way). Our easy-going baby had become VERY fussy. After about 1 1/2 - 2 weeks of these symptoms, I finally decided to check out reviews online, and I'm kicking myself for not doing this FIRST. I can't believe how many other people have experienced these same issues, and I further can't believe the fact that there is SUGAR in this formula! No wonder she would get a "second wind" when we were getting her ready for bedtime! We replaced the "Organic" formula with Similac's "Advanced" formula ASAP (last night). She ate her entire bedtime bottle with no bouts of pain, she fell asleep immediately after eating, and she had a normal stool already this morning. I wanted to do the "Tummy Guarantee" program, however, we threw away our receipts - per usual. So, instead, I hope to warn other moms and dads of this particular formula. Though we do NOT recommend this formula option, we do like the Similac brand.

Rated 5 out of 5 by from Love it This is my second time using Similac Organic on baby #2 I love how it doesn't have all the harmful ingredients as compared to other formulas. It does mix grainy however if you prepare enough formula for what your baby eats in 24 Hours by boiling your water for 1 minute then putting in blender and mixing well it desolves formula completely with no grainy leftover then you put in cold water to cool off and put into refrigerator my baby loves it thanks Similac for Making Organic

Rated 3 out of 5 by from great idea but not great for our baby I was sad that we had to supplement with formula but it was a consolation that there was this organic option. Our (then) 2 week old) tolerated the regular similac non-gmo formula just fine so I didn't compare ingredients when we bought the organic formula. After a few miserable days and nights of a very fussy baby who wouldn't sleep, we switched back to the regular and she settled back down. That's when I looked closer at the ingredients and noticed how different they were. I don't know what she didn't like but unfortunately she didn't like something. Plus the formula didn't seem to completely dissolve - it looked grainy in the bottle no matter how we mixed it up. That was concerning to me. For now we are back on the non-gmo stuff but I'd like to try the pure bliss - seems to have the same ingredients as the regular formula. I wonder if there's a way to get a sample? I hope Similac continues to create and offer options like these. I'd love to see the similac advance non-gmo made with organic milk.

Rated 1 out of 5 by from thick My daughter gets mainly breast milk with occasional formula. We did the organic for about a week and in this week she didn't have a bowel movement for three days, when she did it was so thick it looked like she had been food, and now it all makes sense why she went from sleeping 6-7 hour stretches to 2-3 due to sugar being in this. I have used other similac before with no problem but wow what a difference. Throwing out a basically whole tub of this what a waste of money.
