Here's a great idea to save on all those glasses and cups with your kids wanting something to drink every hour when it's hot outside.  Save those water bottles and reuse them.  Put coolaid in them and put in a basket in the fridge.  Great for picnics or beach time, and you don't have to bring them back to wash them.  Unless of course, you want to reuse them again. 

You can even make so many up for one child and so many for the other.  Take a marker and write their name on them and put them in separate baskets in the fridge.  Once they're gone for the day, that's it.  Quit having to wash cups and glasses all day long because no one wants to reuse the same glass.
