Sharing Shakes

One of our favorite summertime treats is limeade shakes!  Simple ingredients: lime juice, ice, water, and a bit of sugar blended together are so tasty!  I give R and C their own cups and share mine with little H.  The only thing I didn't count on was how much little H would enjoy this shake...she kept asking for more! :)  Next time, I think everyone will get their own cup!  What are your favorite summertime treats?
