Amie put the big bulk diaper carton to good use:
I buy diapers and wipes in bulk at Sam’s Club. If you cut the top flaps off of the wipes box, you can fill it with about one bag’s worth of diapers in three stacks across. Add your bag or tub of wipes and your waterproof changing pad and you have a nice-sized caddy complete with cut-out handles. I even have room to add diaper rash cream if we need it. At one point I considered covering mine with wrapping paper to make it prettier but who has the time? That’s why we need the hacks!
