As the proud father of a band new baby girl – as of this writing – I am also a devoted purchaser of diapers. It’s really incredible how many diapers a newborn or infant will go through in any given day. If you’re a parent, you *know* what I’m talking about. If you’re not, you simply have no idea. This is why I am so happy that Costco makes diapers.
My local Costco carries both Huggies and the Kirkland Signature diapers. Both work very well, but considering the volume we’re talking about, the house brand wins, hands down. Since my baby is still very small, I will start by reviewing the smallest diaper size Costco makes, the Kirkland Signature Supreme Diapers Size 1-2, for infants up to 15 pounds.
In terms of quality, and being leak-proof, I would rate the Kirkland Signature diapers on par with the leading brands. I guess that would depend on the child in question, but I’ve had both a both and now a girl, and they work fine for both.
One thing to consider is that Kirkland Signature lumps the size 1 and 2 in a single size, as opposed to other manufacturers, who will sell you separate diapers for the 1 and 2 sizes. This has the advantage of cutting down on costs, as the diapers get more expensive as they go up in size, but has the drawback of making the diapers quite large for infants, relatively speaking.
That being said, if you just fold the diapers at the front before securing them with the attached Velcro tabs, you’re fine, unless the baby is very tiny, such as less than 6 pounds. Our daughter was about 8 pounds when born, and we used one box of Newborn Pampers we had ( very expensive by the way) and went straight to the Kirkland Signature Diapers Size 1-2 with no problems.
Performance-wise, these diapers have all the bells and whistles you would expect from the major brands, including the color-changing bar that tells you if you’re darling child has wet him or herself, the stretchy leak-proof waist and legs and of course, the super-absorbency that will let your child stay nice and dry, unless she poops, which mine does a lot. Between you and me, I can’t imagine letting my child sit in her waste for any length of time, but that’s neither here nor there.
As far as price goes, the Kirkland Signature Supreme Diapers Size 1-2 costs $19.99 (Canadian) for a box of 136, which translates into just under 15 cents per diaper. This is a really good price. Other brands are usually in the 20 to 25 cents per-diaper bracket, unless they come on special at Costco, and then they’ll more or less match the Kirkland Signature price.
The bottom line is this: if you really like Huggies, buy them at Costco when they’re on special. Otherwise, buy the Kirkland Signature diapers. The money you save compared to buying them at the pharmacy or elsewhere, over a year, will by itself more than pay for your Costco Executive Membership.
Update – March 5th – The Kirkland Diapers are on sale at Costco! The 1-2 Size is $4.25 off per box, and the bigger sizes, $7-8 rebate! This is very timely indeed. I’ll be buying all my diapers for the next 2 years now.
