Hi K.,
My boyfriend and I have twins that will be 2 in Septmeber. We tried all the generics when they were younger (since we had double, spending as little as possible is HUGE) and hated all of them. The ripping off of the tag was a problem we encountered frequently, and given we went through them so much, wasting them was unacceptable.
With the WalMart brand, we had diapers that came out of the package with the tags glued together, cut off, or partially detached right out of the box! Trust me, it's a good way to get pissed in the middle of the night...
I know the diapers change as they get bigger in size, so I don't know if the same problem would occur with a size 4 or larger. Our problems were in newborn to size 1 or 2 (depending on brand).
We used Luvs for a long time but have recently switched to Huggies because it seems the price has dropped on them.
Also, we registered at the Huggies website, and they send us coupons through emails that help. Luvs has recently sent us some, too. We also use generic wipes and baby soap as a way to increase our diaper allowance. AND we started going a little longer between diaper changes once they got a little older and were no longer getting diaper rashes.
Good luck!
