Similac Alimentum Reviews

Rated 1 out of 5 by from Food allergies with Eczema Our son is 9 months old and was breastfeed exclusively till 8 months when my supply ran low. He was diagnosed with eczema around 4 months which we used an elimination diet to help. We found that He couldn’t tolerate Dairy or eggs. We started supplementing him w/ enfamil Prosobee Soy formula but when we made the complete switch to strictly formula we noticed more eczema outbreaks that were becoming unmanageable. When I mentioned this to our Pediatrician she recommended the Similac Alimentum. I went out and purchased the lg powdered formula and made an 8oz bottle for his next feeding, he drank 4oz then instantly threw it up followed by a massive diarrhea diaper 20-30min later. He continued to spit up for the following hour I could only assume until he got it ALL out of his system. I can only assume from some of the prior comments that maybe it’s a corn allergy. I will not be buying this product again. Hopefully the store will take it back, if not I’m out $40.

Rated 5 out of 5 by from No More Crummy Tummy We tried and failed with 4 other formulas on my little one and Alimentum RTF was the only one that she tolerated. I really miss the $5 printable/emailed coupon though. It made her formula affordable.

Rated 4 out of 5 by from Only Formula My Daughter Could Tolerate We tried 8 different formulas, including the Alimentum powder, and my daughter projectile vomiting all of them before we found Alimentum ready to feed. This was the first formula she was able to keep down, therefore, we suspect my daughter has a corn intolerance. Based on this, I'd give the formula 10 stars!! However, in the two months (roughly 50 bottles of ready to feed) that we've use the formula there has been 4 incidents where I've had to throw a brand new bottle away due to it being spoiled when I open it. The first time it happen, my daughter screamed and yelled and refused the bottle. After multiple attempts during that day, I took my daughter to the pediatrician thinking something was wrong but he didn't find anything wrong. My pediatrician suggested I open a new bottle of ready to feed and she if she'd take it, sure enough she sucked this bottle down with no issues. When I compared the contents of the two ready to feed bottles, the one she had refused appeared to be more yellow in color and no matter how much I tried to mix it, it still separated. The formula is expensive, but well worth it if my daughter is happy and eating! But if roughly 8% of the product I purchase goes to waste, mommy is not going to be happy! I'm hoping this is just a fluke and maybe I bought a bad batch???

Rated 1 out of 5 by from Power isnt the same as ready to feed My baby has been on similac alimentum ready to feed for 2 months with no problems. Over the weekend i switched her milk to the powder for the second time and my baby has broke out so bad both times. i just switched back today but have a appointment this week to figure this out.

Rated 5 out of 5 by from Truely the best formula for protein sensitivity! I cannot day enough good things about this formula. After trying almost every kind of formula out there for my daughter who had trouble eating, would scream constantly, struggled with severe constipation and had horrible reflux we finally landed on Alimentum! Our little girl always cried around feeding time because as soon as any other formula hit her tummy she was in pain when we gave her the first bottle of Alimentum she drank a little and prepared herself for pain she started to cry and then stopped and couldn’t drink the bottle fast enough I cried and cried since she was born we had never seen her enjoy eating. Now not only does she enjoy eating but her other issues were resolved as well no more constant screaming, no more constipation, and it significantly improved her colic. She finally smiles and is a happy baby! This formula saved our little girl from being miserable and we can’t thank Similac enough! She is happy and still thriving on Alimentum, thanks Similac!!!!

Rated 5 out of 5 by from Our Colic Cure A few weeks after bringing our first born home we realized that colic was a real and horrible issue that plagues newborns. After nights of nonstop screaming, many tears and trying everything there is to offer, our pediatrician recommend Alimentum. We noticed a difference that very night! The nightly screaming fits that lasted at least four hours were gone! In one day! Our sweet son Leo has been on Alimentum for almost a month now and the difference is night and day. Our new family is able to enjoy every minute together instead of dreading nighttime’s. I cannot thank you enough for this amazing product and making a new family feel back in control.

Rated 4 out of 5 by from Wonderful formula; horrible bottle After trying multiple formula, we finally settled on the Alimentum Ready to Feed for our son who was struggling to keep any and all formulas down due to reflux. It worked wonders, not only could he finish a whole bottle without pulling off the nipple to cry but he spit up much less. He was finally able to put on weight, sleeps easier and is so much happier. The only reason I can't give 5 stars is the terrible bottle design! Every time the bottle is opened formula spills over the lip and out of the lid so we end up losing formula. I wouldn't mind so much but it is really expensive, so we now transfer from the original container to a different one that doesn't leak.
