Sally,

We live in Tx.  I have Gatorade in the nurses office in case our son needs it.  Sometimes I send Gatorade instead of water on hot summer days, and especially on outdoor field trips.  In the lunchbox, sometimes I pack Gatorade, instead of Juicy Juice.  (lunch is after P.E. and recess).  I would rather a few extra calories than a salt wasting crisis.  BUT....that’s my personal opinion!
