Hello, I wanted a post that talked about this subject. As I have a daughter of 23months who was born with the single sided deafness. I wanted to hear from other parents, what experiences that you may had or have with your child's behaviour, or maybe other illness that have co-insided with the single side deafness as my daughter may have Facial nerve palsy a Damage to the facial nerve either upper motor neurone (umn) or lower motor neurone (lmn) produces weak muscle of facial expression. This is due to her single sided deafness but the doctors have not told us what the nerve weaken is or why they think she has this, as her facial features are normal and no one can see anything that gives us a sign. At first we thought its because we are her parents and that's why we can't see what the doctors are telling us. But when talking to a health visitor nor could they see it. My daughter does a lot of head shaking lately, it comes a bit like its an un control movement. Also holding head fingers in her ear.
So any advice please or related stories are welcomed
