• This upset my infant's stomach so much he would scream with gas pains. We quickly switched to a different Similac formula and the screaming stopped. Jun 25, 2019

  • We love all the similac formulas. They are similar enough that we can switch between whatever is available in the local market without upsetting baby's tummy Jun 17, 2019

    This was hard on my baby’s tummy. I didn’t see much of a difference with the Pro Advance and this. I like that it’s closest to breast milk and contains probiotics. I don’t like the added corn and soy. Jun 13, 2019

  • This made my sons burps and farts smell so bad he literally would go worst than an adult we switched to Enfamil Gentlease Jun 10, 2019

  • We did not like the ingredients in this one! It also gave our child severe gas, bloating, reflux, etc. May 17, 2019

    My daughter had to use this with her GERD/acid reflux issues. If not for this formula I don’t know where we would be! May 03, 2019

    Had no problems switching my baby from breastfeeding to this formula. Apr 24, 2019

  • Our son has a sensitive stomach and we tired a lot of the organic formulas but always came back to this one. Cringe when I look at the ingredient list but it's the only one he liked. Apr 13, 2019

  • We noticed a difference in gas and discomfort within 1 day of switching! Mar 10, 2019

  • This is the only formula that we use. Mar 01, 2019

  • Greatly cut down on my babies spit up. Pricey but worth it being that it’s “close to breastmilk” and makes our baby happy! My only complaint is, I wish it wasn’t so foamy. Mar 01, 2019

  • Corn syrup based formula that upset our LO's stomach even though it's supposed to do the opposite. Feb 22, 2019

  • Great formula. Feb 19, 2019

    Did not agree with my little one. He was more gassy, fussy and uncomfortable. It made it difficult for him to pass gas. If also caused him to spit up a lot. He did better on the Pro-Total Comfort. Feb 16, 2019

  • Love Similac. Pricey, though. However, I've heard from a parent that Similac is the closest to breastmilk that formula can get to, so you def get what you pay for. Jan 28, 2019

  • I tried SO many formulas with my son and this ended up being the only one he would drink and that didn't make him too gassy. Jan 28, 2019

  • My LO started out supplementing with total comfort, which was OK, but he spit it up quite a bit. Tried the pro advance and projectile vomited it. This stuff has been great. He's gassy but poops fine Jan 15, 2019

  • This obviously all depends. It does what it says; gas was relieved, gas pains went away but baby became terribly constipated. Screaming and crying. It was heartbreaking. So we changed. Jan 10, 2019

  • This stuff is supposed to help with gas but it's so foamy! Over half the bottle fills with bubbles! Jan 10, 2019

  • My daughter supplements with this formula and she does extremely well on it. Jan 03, 2019

  • My daughter did very well with the pro sensitive formula. Dec 08, 2018

  • So far so good with this formula. My baby hasn’t had much spit up while on this and seems to not have many gas issues either like he had been having previously. Oct 02, 2018

  • Used to have a little one that would struggle passing gas, and was just very fussy. Since using this product she has calmed a significant amount and has had no more tummy problems. Sep 16, 2018

    This was recommended to me by my LO's pediatrician and it made my LO so constipated and she was constantly uncomfortable. Sep 12, 2018

  • We began buying this because Similac sent us vouchers. We use this as a supplement to the breast. We've not seen any stomach trouble with this formula so there is nothing to regret. Aug 28, 2018

  • We used this for the first 8 weeks with the twins, they still had some gas until we switched to a store brand version Aug 27, 2018

  • This made my son so sick and he choked and spit up all the time because of it Aug 14, 2018

  • My little one has been on this since day 4. We switched him to this formula because he was loosing too much weight. He was able to gain weight back and has no tummy trouble with this formula. Aug 10, 2018

    This is the only formula that works for my baby. It does create a lot of bubbles so we mix it in another bottle first and then pour it into the bottle my baby drinks from. Jul 18, 2018

    great for gassy babies Jul 09, 2018

  • Love this. Made him less fussy. Can get a great deal at Sam's Club and there are Ibotta rebates available. Jul 07, 2018

  • Used this for my daughter from day one. No complaints. I even got my sisters to switch to similac Jul 02, 2018

  • Compared to the Enfamil Gentlease I like this better. Fills my newborn up and she is less gassy. Still looking for a formula to solve her colic though. Jul 02, 2018

  • We switched from Sensitive to Pro-Sensitive and I love it, I really do believe its helping her immune system Jun 21, 2018

  • Honestly my daughter actually had stomach issues on this formula even though it’s a sensitive formula! She does much better on the regular pro advanced Jun 21, 2018

  • My baby was having problems with throwing up and stomach cramping that would keep her from napping. I switched to this and it went away. She is more comfy and throws up less. It makes a big difference Jun 13, 2018

  • Similac is a great brand- and the coupons your receive from signing up on their website is SO HELPFUL!! But unfortunately our LO dealt with too much gas from this- her stomach lining was too sensitive Jun 09, 2018

    Used only this (after switching to sensitive) and it was great - my sensitive tummy baby loved it and I loved when they started the HMO additions! May 31, 2018

  • Switched from Neosure and LO has had no issues so far. Only negative is that it's super foamy when you mix with water. He has had less spit up and when he does he hasn't cried like with Neosure. May 27, 2018

  • Our little guy is currently on this after having Pro-Advance ready-to-feed in hospital. We switched to this because we noticed he was having gas issues and this seems to alleviate that pain for him May 15, 2018

  • Great. This is what we had our daughter start on, but since it is very expensive we switched to a brand name formula. May 02, 2018

  • My baby is picky and has not rejected this formula. Apr 21, 2018

    This formula works well for my son with reflux, stays down better than regular similac formula. It does get foamy but that doesn’t bother him. Mar 24, 2018

  • Lyra loves it! Sign up for coupons on their website to help save money. =) Mar 22, 2018

  • We used this because baby boy was super gassy on regular similac. This formula is SO frothy. You can't just shake the bottle up to mix it as it's then 50% foam! Also, not sure it helped with gas. Mar 20, 2018

  • My baby took to this very quickly without fuss or gassiness! Feb 07, 2018

    • Mary C.
    • Milwaukee, Wisconsin

    I love this formula. I mix this half and half with Similac for Spit-Up to avoid constipation from the rice starch. It's pricey but worth it. Feb 05, 2018

    • Sara M.
    • Rochester, Minnesota

    This is a great formula when I wasn't able to keep up with breastfeeding. After doing a lot of research, I found it to be a great fit. The smell is fairly neutral and my baby has no extra gas. Feb 05, 2018

  • I made the switch from breastmilk to formula but were worried it would upset my daughter's belly. This formula has been easy for her to digest. It does bubble a bit when mixed but overall we're happy! Jan 29, 2018

  • We were using this for a long time because of gas. It had a lot of bubbles and he threw it up a lot. It also stained clothing. Jan 23, 2018
