I got some samples of their different diapers through a friend who is a member, and they were actually pretty terrible for my little guy. Every poop diaper had some poosplosion out the top or sides to it, and he got horrible diaper rash with his wets, even though I changed him like I normally do. That said, he's long and lean, so we had some issues with poop leakage on the Pampers too- the Target brand fits him the best, so I might not be the best person. They sent formula samples too, but what they sent me was already past the expiration date (not great marketing on their part!) so I didn't try that.
I believe Kirkland brand diapers (Costco) are made by the same manufacturer as Huggies. They're similar to their diapers so if you like Huggies, the Costco brand will probably work (and probably be cheaper). I used them with DS1 when he was in a bigger size and his poo wasn't as runny as it is at this age and they were decent.
I'd be willing to bet their formula is also produced by the same manufacturer as one of the big brand names but I don't know for sure.
Love the diapers! They are soft and work great. Yes, we have had some poo explosions, but I chalk that up to her holding it in for 6 days before letting it ALL out... As for formula/wipes, haven't tried those.
I haven't tried their diapers yet, but I have a box. She just isn't that size yet. We exclusively do Costco formula now. Huge container for $17. I compared it to Similac and it was nearly identical. Our pedi said it was fine to use. She hardly ever spits up with it.
Love their formula, used it for both boys and it is 1/3 retail price of Enfamil. Tried their diapers with older DS and didn't care for them. Maybe makes sense if they are similar to Huggies since we now just stick to Pampers as they seem to fit our boys best.
I found the costco diapers similar to Huggies but they fit her better and also have a wetness indicator. They are my second choice next to pampers which fit her best

Do they offer different varieties of formula? DD takes Gentlease and would need the generic of that.
