This is more organizational than mini-style, I suppose, but since it's clothing specific....

If you have same-sex twins or siblings close enough in age to wear the same clothing size, how do you identify what clothing belongs to which child? My oldest two DDs (soon to be 5 and 3) have hit a point with summer things where they pretty much wear the same size - and they both will have items in their drawer ranging anywhere from 24 months (shorts!) to as big as 5 for the older one and 3 for the younger...with plenty of overlap on the inbetween sizes. I basically know whose is whose, but when other people like DH or MIL try to help me with laundry, it becomes a disaster.

So do you mark tags? What about tagless items? I feel like it's silly to use our Oliver's labels we buy for items like coats/water bottles on things as trivial as undies and cartwheel shorts.
