We switched from Similac Advance after 1 month of bottle feeding, and noticed a significant change in stools.  The Similac was much softer and seedy, whereas the Cosco's Kirkland formula was uniform and much harder.  This was accompanied by strain and crying during bowel movements.  All of these are signs of constipation, requiring adding water to the diet, which is not normal for a 1 month old.  This change was 100% correlated to the formula, and we even switched back after a month of using Costco's Kirkland formula to Similac when we ran out, and the very next stool was back to normal.  If you search online, you'll find several other people who experienced this same problem.  We solved this originally by giving 1oz of water to our daughter throughout the day.  However, I tried switching 1/3 of the Kirkland forumula for Similac and this seems to have corrected the problem as well, and is still much cheaper than switching to Similac alltogether.  Another difference between the two is that Cosco's Kirkland formula is very foamy when you shake it up and this doesn't go away, leaving lots of foam at the bottom of the bottle.  Similac is foamy initially but they have some ingredient that cuts it down as the baby eats.  Switching 1/3 of the forumula with Similac got rid of this problem as well.

I'd been supplementing with Enfamil Lipil since my son's birth, and four months down the line I figured I'd try the Kirkland formula instead and save a little money.  Bad idea.  It's much more powdery than the Enfamil, making it prone to caking and clumping during measuring and mixing.  It creates *much* more gas during mixing as well, which does not settle out very quickly, so you have to make it up much further in advance to reduce the amount of air taken in during feeding.  In addition, the color is much more intense (and therefore staining), and the smell is awful.  My son doesn't seem to like it, either; he has been a lot more fussy since we tried it, fighting the bottle and spitting up much more often.  I'll be attempting to return my unopened can and switching back to Enfamil ASAP.  At least Costco has a good price on that as well.

Stay at home dad with 4 month old.

Comments about Kirkland Signature Infant Formula with Iron:

We supplement our daughter's diet with Kirkland formula while my wife is at work. My daughter seems to enjoy the taste and guzzles it down heartily. I will admit that the formula does have a bit of an odd odor as others have commented, so it is kind of sad when my little girl loses that sweet, breast-fed baby smell and smells like a formula baby instead.

Ultimately, we settled on this product because it is the most inexpensive one we have found, and that is a huge selling point for my family during these uncertain financial times. However, we don't feel that we are sacrificing quality and are confident that our baby is getting the nutrition she needs.

Easily Digested
I haven't noticed any digestive issues. My daughter has regular bowl movements and doesn't get to be too gassy.

Ease of Preparation
It is quick and easy to prepare, and I haven't noticed any real clumping issues. It mixes smoothly with water and easily passes through the nipple.

What a wonderful product!

By 

from USA

Comments about Kirkland Signature Infant Formula with Iron:

This baby formula was the most reasonably priced around! All three of our children supplemented with formula at some point during their first year of life and after trying the various samples that were sent to the house or received from the hospital, we ended up using Kirkland Formula exclusively. There were no issues with any reaction or intolerance to this brand and it was exponentially cheaper than the other options available. Our pediatrician was so pleased to learn we were using Kirkland to supplement and said it stands up as an excellent product with years of good reviews and successful use for many of the babies seen by the practice. Why spend more on other name brands if you don't have to? Yes, we were fortunate not to have to deal with reflux or allergies that require the use of prescription formulas. That fact allowed us to choose from a wide array of formulas on the market and this one worked so well we kept coming back to it with each new baby we welcomed!

Cheaper than other brands

Comments about Kirkland Signature Infant Formula with Iron:

The kirkland brand formula is cheaper compared to other leading brands, but it matches the specifications set the the FDA and since it is for babies it cannot go wrong. Also, this doesn't give much foam when mixed with water unlike other brands. We have been using this for the past 3 years for 2 kids and we never had any issues. It is very easy to mix and the powder dissolved very quickly. I would highly recommend this formula. This is available in bigger size so it doesn't run out quickly and is also cost effective. Make sure to loosen up the powder upon opening a new can. I failed to do this recently and the first batch of formula I made was too concentrated. Lucky for my son, I caught this before he drank more than an ounce or so! After tipping the can back and forth, it loosened up and mixed up perfectly. Overall it is very nice formula. Thank you costco for providing good product for a low price compared to other leading brands.

Great Formula, Less Gas

By 

from Undisclosed

Comments about Kirkland Signature Infant Formula with Iron:

I started using this formula after switching from the Similac infant formula which gave my babies terrible gas. Now this is still gassier than my breast milk, but it is miles above the Similac. I was first drawn to the price, which is fantastically cheap when you compare it to any of the name brand formulas out there. I have twins and so go through twice the normal amount of formula, and price is something I need to be very conscious of.
Out of all the formulas I have tried these give my babies the least amount of gas, particularly when I let the bottles sit for a few minutes and let the bubbles disappear before I feed it to them. If I add a small amount of gas drops after I initially mix up the formula, then it works even better and my babies have hardly any gas afterwards.
I love the size of the containers, we go through one every 6 days, which is a couple more days than it takes to go through the smaller, more expensive formulas that don't work as well for us.

seemed ok, but not for my baby.

Comments about Kirkland Signature Infant Formula with Iron:

My baby had milk allergy issues, he was sensitive to certain formulas, this one was a back up, but still gave him gas. It was easy to mix, just the formula wasn't right for my son. If you needed a basic formula for a child, this one should work. I think all the store brands carry the same ingredients as the name brands, so it should be comparable to the vitamins and nutrients. It was a whole lot cheaper than the brand names for sure.

Easily Digested
This formula upset my baby's tummy. He still had gas and some problems digesting it. We had to switch to another formula. If your child isn't lactose sensitive, maybe it would be okay?

Ease of Preparation
This Kirkland baby formula was easy to mix, but became a bit frothy if we shook the bottle too much. The best way we found was to mix in a separate container and then we poured it into the baby's bottle after the foam settled down. But of course, that doesn't help too much when you are on the go...

Kirkland makes quality items with a generic name

By 

from USA

Comments about Kirkland Signature Infant Formula with Iron:

This formula is the pretty much the same stuff as Similac, my doctor even suggested so. It is a great value for the amount you get and is super easy to make. We would buy several at a time but they would last us awhile since the containers are so large. The sizes you buy a normal grocery store would only last us a week if that. The powder breaks up nicely in water unlike some other powders that I shake and shake and it still is clumpy. I would have preferred that my baby be breast fed but I am happy with this alternative option. I felt that she was getting all the nutrients that she needed to grow healthy.

Easily Digested
My daughter has never had a problem with this formula but she also doesn't have a sensitive stomach or any sensitivities to milk. For someone that needs generic stuff, this is the best option.

Ease of Preparation
This is super easy to prepare. It dissolves into water very easily and doesn't leave clumps.

Just as good as premium name brand formulas

Comments about Kirkland Signature Infant Formula with Iron:

This formula is just as good as all the premium name brand formulas on the market and will save you a ton of money. My daughter was breastfed for the first three months, then I put her on Gerber Goodstart for one month, then I transitioned her to Kirkland formula. She had no problems with the transition. In fact, she started sleeping through the night shortly after starting Kirkland formula. Not sure if that had anything to do with the formula, but I'd like to think so! The only downfall that some people complain about is the amount of bubbles created when shaking the bottle to mix the formula, which happens to not be an issue for my baby. The bubbles can easily be avoided. I like to mix up a large batch every morning, keep it in the fridge and pour into bottles as needed. Using that method, you can avoid bubbly bottles. I've used this formula with both my kids and they have never had any gas or constipation issues. The container is much larger than premium brand largest containers, so this means less trips to the store to buy formula. This formula is the best value for you money!

Great Alternative to Name Brand Formula

Comments about Kirkland Signature Infant Formula with Iron:

Kirkland Brand Formula is a great alternative to name brand formula. My husband and I started our 1st born out on name brand formula because that's what the hospital gave us. We used it for the first six months of her life, and we were very happy with the name brand formula, but the price got to be too much. The name brand formula we were using was twice as expensive as the Kirkland Brand.

Easily Digested
The Kirkland Formula is a little bit more frothy than other name brand varieties. Since we started our baby on the Kirkland Formula at 6 months, she has had no problem with digestion, but I would be a little concerned giving it to a new born because it could cause excess gas or spit ups.

Ease of Preparation
The formula is easy to prepare. It is a little bit denser than name brand formula, meaning it does not start mixing in right away, but once shaken, the formula mixes in well. The Kirkland brand uses the standard 1 scoop for every 2 oz.

Kirkland Infant Formula

By 

from Harrah, WA

Comments about Kirkland Signature Infant Formula with Iron:

I am the grandmother of eight, the youngest is just four months. My youngest daughter inlaw had used Similac and Nestle's Good Start with her first three, the fourth was not able to tolerate those products. He has a problem with reflux and it seemed in his first two months the other products would not agree with his system. She tried the Kirkland Infant Formula when money was a bit tight at the end of the month and in addition to being less expensive, it's staying down, it's less "curdling" and less pungent when he does have burp-ups. My grandson also doesn't have the constipation and gas problems he had before. It mixes quickly and he seems to really like it, so I would say it's a win-win situation all around!

Love this baby formula, love the price

By 

from Ogden, UT

Comments about Kirkland Signature Infant Formula with Iron:

I fed my baby formula once a day from the time he was 4-months old and exclusively from the time he was 9-months old.  I tried several different brands (including name brands) and I liked the Kirkland Signature Infant Formula as well as any of them.  The price-tag, however, beat out any of the name brand formulas hands down and most of the other store-name/generic formulas.  I like that this one did not get super foamy like I had experienced with a few other brands and it didn't have as potent of a smell.  He rarely had issues with spitting up, it didn't seem to upset his stomach, and he transitioned to this formula easily...and then again from this formula to cow's milk with no issues.

The thing I liked most about this formula was that it has DHA and ARA.  As I compared the vitamins/nutrients found in this kind it had everything that was important to me that my child get on a daily basis.  I was confident that aside from breast milk, this was the next best thing for my baby.
