Didn't pass hearing test! 😣

My 2 week old didn't pass his hearing test on his left ear! He was tested twice when he was two days old, and he didn't pass on his left ear, but the right one did, So they told me to take him in again in a week to re test him. I took him today, and he still didn't pass! 😢 they sent me to childrens hospital with a specialist.! Im praying to God it's nothing to serious, and just be a little fluid! Has any one experienced this with their little ones??
