Thank you for your query,
As your child didn't pass urine for almost a day it is suggestive of dehydration
Continue to give Pedialyte
approximately 50 to 100 ml after each loose stool
and sips in between the stool also.
Continue breast feeds frequently.
Don't use any medication without prescription in infants as it is not safe.
Consult a Pediatrician
immediately near by you for the assessment of dehydration and for appropriate management.
Hope i have answered your query.
