Hi Experts, My 21 days daughter (Birth Weight - 2.3 kg) hasn't cleared the hearing test in left ear. The test has been done twice. The pediatrician has suggested to wait for another 2 weeks and get the test done again. He said that maybe the left ear is not fully developed. I m very tensed about it. She responds to sounds but how do I know If both the ears are functioning properly? Also, what should be my next steps medically?
