The family photo idea is a great one!
We met a family (the mom is a pediatrician) who wrote the cell # and some other info that I don't exactly remember on the kids legs with a permanent marker! I thought that was a quick, easy and cheap solution!

It's not the most flattering thing, but wow! It's much easier to spot the tie-dye design in a crowd than a solid-color shirt, and if one kid wanders off, you can tell any CM to look for a kid in a shirt just like yours.
