Talk to Pediatrician on 1 Year Old Starts Crying Non Stop At 3 AM

My 1 year daughter fell sick 3 4 days ago and had a mild fever possibly due to throat. She was treated with NSAIDs but no antibiotics. She is not feverish anymore but since then she wakes up between 3-4 Am, and starts crying at the peak of her lungs. Nothing soothes her, after 10 15 minutes, stops and sleeps but again after a few minutes starts the 2nd time. Apparently, there seems to be no issue, no gas or constipation, AC working, fed properly before bed. She also does not look frightened as her symptoms do not look so. Other than this she is a happy & joyful kid
