Any age 1 year old and above can drink pedialyte.
For a child 1 year old and older give them small frequent sips of the pedialyte every 15 minutes.
Continue to give them pedialyte until they've recovered from being sick of having diarrhea.
Even adults can drink pedialyte as well it's not just for toddlers and children. I drink it myself when I'm sick with the flu or have diarrhea.
