Help help

To all mama out there,

My 9months baby girl has yeast diaper rash + viral infection. She has not be able to urinate for almost two days. I took her to the emergency and doctor said she looks okay, not dehydrated. Then she asked me to wait for one to two days to see her pas urine. But i am super anxious and worried because my first one had uti and dehydrated which i didn’t know. The my first daughter got seizure because her fever got too high. I don’t want the same thing happened again.

Anyone out there had experience this, can you give me advices how to help her pass urine nature way?

Thank you so much
