Are they at least paying for the shipping for you to send that pack of diapers back?
As for diaper brands - I stick by Luvs! I don't like anything else. In fact, I've been using huggies overnites since LO sttn, and while they don't leak at all the tabs on them rip off a lot. It seems like 1 out of 3 of their diapers has that problem, and I'm not rough with it at all.
