I don't know about your kids, but MY kids can go through too many cups/glasses in a day! Today, we started something new to help solve the "get a new cup, everytime I need a drink" problem.
Around Christmas I purchased some Window Crayons and they were awesome for the kids to decorate the windows. They had a blast, I posted about it on My Family Blog So, today, I decided that the kids could decorate their glass, and call it their own...for the whole day! They have been so proud to "reuse" their own special cup today...I will do this each morning to save dishes and dishwasher space!!!
