Early on I found that my little one has a sensitivity to lactose (not an allergic reaction - just sensitivity) and didn't tolerate regular formulas well. Initially she was breastfed, then supplemented, then eventually I decided to exclusively formula-feed as I couldn't keep up with her needs as she grew and couldn't increase my milk supply with all the professional help imaginable and decided it was in her (and my own) best interest to spend more quality time together and to be 100% certain she was always fed well.

I've learned a lot since then, but at first I absorbed a lot of guilt from extremely zealous "lactivist" types (other mothers, lactation consultants, etc.) who sometimes spread a great deal of misinformation about the size of neonates' stomachs, the quality of formula, and the merits of breastmilk and breastfeeding itself to keep women breastfeeding at any cost. Breast is good, sure, but it isn't best if children suffer due to insufficient feeding. "Babies experience hunger as suffering" is one of the most important statements I have ever read. The truth is, what is best varies.

Just a little tip: if your baby constantly nurses around the clock (read: is never satisfied and wants to remain constantly latched to the breast,) this is not "clusterfeeding" or simply "a growth spurt." If never satisfied, the baby isn't getting enough milk and if you do not act quickly to address this, your baby can experience significant harm. All that said to say this: contrary to what these lactivist-types would have you believe, the fact is, a decent percentage of women cannot produce sufficient milk to exclusively breastfeed, and infant formula is safe, rigorously tested, and healthy. Read about it. Formula is good and, sometimes, it's best.

Anyway, end tangent. I just hope to help another mother who has experienced pressure from others to trust her own intellect and instinct.

My baby started on Enfamil Premium Newborn. I switched to Gentlease then finally to Similac Sensitive, which has less lactose and contains protein ISOLATE which is easier to digest, even for adults, than whey protein "concentrate" found in Gentlease. (Ask any health nut, bodybuilder, or dietician and they will say the same.) The difference in my child was night and day after the first feeding. No more feeding issues. Very little spit-up now, which only occurs occasionally and directly after feedings.

So thankful for this product!

I'm very proud to say that I made it 6 months with breastfeeding my baby but I'm also proud to say that my daughter has been receiving proper nutrition her whole life.  I always knew that I planned on breastfeeding but I also knew that I was not against formula in any way.

It was important to me that I find a formula that I felt comfortable with and be confident in my choice.  My daughter has loved her Similac since we started her on it and we never looked back.  She does very well with this sensitive version since it's easy on her little stomach and it keeps her comfortable and satiated.  We love our Similac and will continue to use it through her first birthday.

My son enjoys Similac formula. Hes never fussy when he uses this formula and he rarely will spit up. Similac Strong mom a program is an online program that has sent me 15$ coupons and that helps so much considering the formula only costs 17$. I've also received free formula in the mail. Everybody is eligible for this program!

This is formula is horrible. Gave my daughter gas and it creates a ton of bubbles. It is basically made up of oils and high fructose corn syrup. My midwife told me that she was going to call corporate and ask them to remove the corn syrup. She also said that this formula might as well be soda 😂

My son had been using similac since birth (it was supplemented for him, since he was in pediatrics the first week) Although, i loved breastfeeding I didn't produce enough milk. So eventually he was switched over to formula for good. We switched to sensitive after he was a little gassy. And between this and gripe water he had no problems.  Plus I found Similac pretty much always has good deals and coupons.

This formula is great for a baby with a sensitive stomach. I was unable to breastfeed and this ended up being a great alternative although it can get pretty expensive. Usually am able to get it on sale on amazon so I recommend checking there for it!

We tried several different cans of Similac and we couldn't find anything that agreed with him. He only spit up with similac. He never had issues with other brands or breastmilk. He tolerated the favor fine but i couldn't take all of the spit up.

I started using this formula for my baby who would get really constipated with the regular blue can so we switch him over to sensitive and he loves it he’s always smiling so I’m guessing the helps fussiness does work lol

My daughter has a mild dairy allergy so after being on nutramigen for months the doctor suggested making our bottles half nutramigen half similac sensitive and then eventually move fully to the similac. She did great, we now have her drinking soy milk (since she is almost 2) and I couldn't be happier about our experience with the similac.
