Diapers fit nicely in the plastic wipes box
Lisa V.'s diapers-to-go hack:
If you have a child in diapers, use the refillable wipes packs (the smaller travel size in the soft package). Put the package of wipes into the original box (the regular full-size box). Then add a few diapers (they fit nicely!) Now you have a pack of wipes and dipes for going out.
I didn't realize they could all fit together so nicely until recently and my son is 2!
I usually come up with the great hack right as my kid's about to grow out of that particular solution. Sigh.
