I have packets of the stuff - but it's not pedialyte. From memory, I bought it in the chemist in a box of about 20 or so sachets. They just have "oral rehydration salts" as the name plus instructions on how to mix them, they appear to be manufactured here by Drug Houses of Australia (Asia) pte Ltd. I'm sure they are widely available.
Good luck in getting your child to take it - mine just throw it up
