Do not buy an economy sized box of 150 diapers without being able to try them first. S-Boogie goes through 3-4 diapers per day, which means we'll be using them up for nearly a month. Unfortunately, Costco only sells their diapers in the enormous box so we took a gamble and lost. I love their baby wipes, but within the last 5 days or so we've had several incidents of leakage from wetness as well as at least one leaky poopy diaper. I'm sticking with Luvs, they make me happy and they don't leak like this.
If anyone wants to buy a nearly full box of Kirkland diapers, email me (it's at the bottom of my blog). They're size 5, so for kids over 28 pounds (I think that includes you, Tolkien Boy :))
