I do not keep them separate, in the VERY begining years ago I attempted with child name on each but found not only was that too many wipe containers in one spot but just too much to keep track of. I do purchase then when they are needed and also put up a note every so often or send a text to parents, asking for a fresh supply. they are always happy to help. and do have the few parents who bring them in every so often with out being asked. only once...I had a mom who traveled about 4 hours away to purchase a specific brand of wipe and asked that only her son use them! she was a pain in my a%$! thankfully she is gone now, but thats another post alltogether. if I were you I would have "community" wipes and just ask parents to bring a pack once every month or two, so much easier!
