Our little guy was a preemie and could never learn to breastfeed so we had to use liquid formula. We tried the blue similac bottles at first. So much has and spit up!! Poor guy would cry for several minutes before letting out man-sized gas. We decided to try these and it’s made such a difference. We ran out of these for a few days and had to use the blue bottles again until these were back in stock and the problems came back. We hope to use these for the next couple of months and then transition to the powder version.

I like being able to order this and have it delivered directly to my house. It’s convenient for when I have my granddaughter spend the night. It’s also what the doctor suggested she take because she was nauseous when she took the other ones and threw up a lot.

I think switching formulas is becoming a popular past-time of new parents these days, and when I look back on our experience with our first baby I'm almost ashamed at how frantically we switched her formulas around, searching for an answer to her gassy, colicky behavior. I think in total we tried 7 or 8, from powder to ready-to-feed, hoping that one would be a magical formula that eased her tummy (and our eardrums) during her fussy evening hours.Unfortunately, none of those formulas worked magic. It ended up being that our daughter's belly really did just need to grow & mature before she could readily digest formula, and even the hypo-allergenic ones made little difference in her spit-up or tummy achin' behavior.However, Similac Sensitive was always our fall-back formula because it seemed to cause the least amount of stomach upset, didn't smell as horrible as some of the others, and with the coupons they send out (from StrongMoms) - it was surprisingly affordable for the most part. Strangely, our daughter would only drink ready-to-feed and would never finish a powder-prepared bottle and did seem more gassy after those. So we had to bite our bottom lips and put out the extra money for the liquid, which though expensive, was also very handy on trips and during late night feedings.Similac Sensitive still has a small amount of lactose in it, but it's broken down more than Similac Advance so it's easier to digest. And since it's already sterilized in the bottle, there are none of those new-parent worries over your powdered formula being contaminated or washing your hands before every bottle you make/feed. Trust me, when you're running on 2 hours of sleep, these "simple pleasures" can really make a big difference. I also called Similac's customer service on several occasions to ask questions and they were polite and helpful, and even sent coupons!We used Similac Sensitive until our daughter was ready to transition to cow's milk, and although we tried cheaper versions and many other formulas in an attempt to save money, we could never find anything our baby would take as easily as Similac Sensitive, so we stuck by it and would do so with the next baby should the need arise.**********UPDATE**********We just had our second child and immediately skipped all other formulas and went straight to Similac Sensitive. This has saved so much trouble from the first time around! Baby #2 is doing great on this formula, however, he has been diagnosed with Acid Reflux. This means feedings are very difficult and painful. The only alternative to try from this formula is Nutramigen, but its too expensive. We are giving baby #2 Zantac prescribed from his pediatrictian and it seems to be helping.It wasn't mentioned before, but if your baby is taking Similac Sensitive, but still having a lot of spit up or acts differently on the powder vs RTF. This is probably because the RTF is much thicker and babies are able to handle it better. The RTF is also much easier to digest than the powdered version because the nutrients have been fully dissolved 100% into liquid. However, with the powder, baby's belly may have to work a little harder to process the powder. Because our children have acid reflux, powder is not an option. The less spit up, the better because stomach acid is brought back up into the esophagus the more they spit up.

The baby is very sensitive and this is the best. For her she isn't as fussy and spitting up

Our daughter showed signs of colic in the first two weeks, so we immediately switched from Similac Advance to the Similac Sensitive. Before she was born, I had purchased a large case of the 2oz ready-to-feed bottles (one of Advance, one of Sensitive) just in case. We had nearly used all of the Advance by the time she started having problems, so I switched her to the Sensitive. It definitely helped. I still had to supplement her with gripe water (we used Colic Calm - my goodness, that product is WORTH EVERY SINGLE PENNY, if you have a colic child PLEASE don't waste any time, pick up the Colic Calm at your local CVS or order it online through their website, it saved us).Here's the catch - after a while, I tried to switch her to the powdered version of the Similac Sensitive. I will be honest here and say that the powdered version ends up thinner, causing more spit up and hiccups. You also have to be careful when mixing it. If you shake it up, it becomes very bubbly with air and causes tremendous amounts of gas. For us, it was as if she had gone back to her colicky ways again. I knew it had to be the powder, so I put her right back on the liquid ready-to-feed and she is amazing again. Sleeping 6+ hours at night, no fussiness, etc. I hope this helps someone - good luck parents!

I know a lot of people come on here and complain it has corn syrup. However, I have tried about 20 formulas and this was the only one that worked for my baby. When you find ones that works, you stick to it. The fact that she is getting nutrients from it and it stays down, that is what I am focused on as a mother. Other formulas made her gag and throw up. Just because she did not like them I am not going to go to the other formula pages and put them down.I have been buying this formula for over a year here. I just received an email that they no longer are doing the Subscribe and Save price. That is sad. The regular price of the item now is higher than my local Walmart store. It was so convenient to order from Amazon and have it delivered to my door. Plus, I would rather give my money to Amazon but as a single mother, I need to get the cheaper price.I hope they decide to add it back to subscribe and save again if enough people write about it. It was so much easier. I guess this will be my last purchase until they either lower the price or add it back to S&S.
