I stocked up on size 4 huggies diapers thinking they would fit for a long time, but I was so wrong. I have a lot (I would guess about 80) and would like to trade for size 5 or even 6 in huggies or pampers brands. They are in package, although it has been opened, that's why I can not return to store for a bigger size. Please email me if interested. Thanks!
