Similac Sensitive Reviews

Rated 5 out of 5 by from Love it!! So my 3 month old has been on this formula since birth. It has worked amazing for him. He had some issued with gas and fussiness and we decided to try some Alimentum and Enfamil Gentlease. It was HORRIBLE!! My son wasnt sleeping, spent hours screaming in pain, and the gas was just intense. We went back to Similac Sensitive and immediately all the extreme symtoms disappeared. He still has some issues with gas but for the most part he's a happy baby and we LOVE this formula. I also want to say we reached out to their customer service to inquire more about the formula and such and they were amazing! They went above and beyond to answer my questions and most importantly, It didnt feel like i was receiving scripted responses which is common with some companys. Thank you similac. Oh and for those commenting on the bubbles or foam. I have found that using a separate bottle to mix his formula helps. When i pour the formula into the bottle he's going to drink from, i can avoid the bubbles. ANOTHER tip, instead of shaking the bottle vigorously and up/down, try shaking from side to side GENTLY, the formula will still mix and dissolve fully but theres rarely any bubbles.Lastly, if shaking it isnt working then stir it with a spoon or something instead of shaking, no bubbles ♡♡♡ My ped also recommended making his formula for the entire day in the am and this allows the bubbles to leave also but i haven't done it this way. Hope this helps

Rated 1 out of 5 by from Terrible product Enfamil Gentlease works so much better for my son! He is less gassy and fussy. I also hate the fact they add sugar to their Sensitive formula.

Rated 1 out of 5 by from This formula sucks I have switched back to this formula 2x but I get the same results with my 3 month old she grunts and gets very fidgety because she’s so gassy from this formula. I’m upset because the doctors said it’s normal. It’s not normal because when she was on total comfort this wasn’t happening!

Rated 5 out of 5 by from Best Overall Baby had stomach issues with breast milk, and after supplementing with Similac, it was like a different baby. I never thought formula could ease the discomfort of breast milk, but this product did it!!

Rated 4 out of 5 by from Its been working for my son so far Hes less fussy and hes a lot happier since this doesnt upset his tummy too much

Rated 4 out of 5 by from This product has worked well for my little one so far. My little one is is 6 weeks old today. He was having very bad tummy troubles, so on his one month check up I told his pediatrician about it. She recommended that we change him to Similac Pro-Sensitive. Now he’s only been on it for two weeks, but I can already tell that he is taking to it better then the Similac Pro Advance. He still is a little fussy, but when it comes to him passing gas he doesn’t strain and get really red in the face as much as he used too.

Rated 4 out of 5 by from This product help with gas So I'm a new mom on my 4th kid and I'm also breastfeeding while giving formula to. I noticed when I gave him Enfamil he is was having gas and was spitting a lot but I never had with any of my other kids. so I switch to Similac Sensitive because I was recommended it and I've noticed a great difference he's not as spitty as much and the pain of gas has gone down but I am giving him breastmilk alot more than formula but I did try the pre-made ones first before I bought the can.

Rated 5 out of 5 by from Amazing product I used this with all of my children ( 4) and never had any issues. Best one I have found, that actually works!

Rated 4 out of 5 by from Good on stomach BUT Since bringing our baby home we tried Similac advance and found that she had a sensitive tummy so we switched to the Sensitive formula. We initially used the ready to use formula for her which we loved but due to the cost we switched to the powder form now that she's almost 5 months. She loves it BUT there's so much foam when I shake it! Is there a reason the powder formula produces so much foam- has anyone else had this issue? I find that the foam tends to make her want to burp more times DURING the feeding. Other than the foam it's a good formula.

Rated 5 out of 5 by from Switched because of gas and fussiness My son was drinking enfamil’s gentlease RTF formula and had horrible problems with gas and fussiness. He never seemed full, He would cry mid bottle and was constantly pulling his legs up and whincing in pain from gas cramps. He was spitting up after eating and was never happy while awake. Since switching to similac sensitive we have a much happier boy! He laughs and coo’s while awake and seems fuller after every bottle. We are very happy we made the switch to similac sensitive and enjoy the concentrate version of the product.

Rated 3 out of 5 by from This product is ok! After trying Enfamil the doctor put my 4 week old on the Similac sensitive. This product helps my son with his gas and fussing, almost eliminating his fussing. But it does not get my son full at all!! I’m feeding him way over the amount that is recommended for his age and he is still not getting full!!

Rated 3 out of 5 by from A lot of foam My baby has gas issues before using this but when I start using powder formula intensity is low but he still has gas problem . I have to wait a lot for the foam to be finished so that I should feed my baby. And I don't find 2 oz bottles of this formula.
Date published: 2018-05-17
Rated 4 out of 5 by from My baby had a lot of gas before consumption of this product. WHEN I started using this product yes it was foamy, I used Match, Avent, Dr. BROWN'S To reduce foam swirl the bottle with the formula, not shake it reduces foam for safe consumption. I also, warm the water a bit before serving, No issues, yes some gas will still be present is norm. Im a mother of 4 kids, breastfed and supplemented with this formula.

Rated 2 out of 5 by from Very Foamy My infant has gas, fussiness, and constipation. It was okay for the constipation, but she cried after eating it and had horrible gas still. I did not like how foamy every bottle was. We discontinued use.
Date published: 2018-05-11
Rated 3 out of 5 by from Using it for a week. Wondering about the foam? My baby is definitely spitting up less, and is less consitpated, but she seems to have quite a bit of gas. I’m wondering if it could be because of all the foam in her bottle when we feed her using this formula? My question is the foam harmful to babies? Could it cause more gas?
