General hints:
How to help the child who may have been diagnosed with a degree of hearing loss:
Speak clearly - use a strong voice, speak naturally and at a normal rate.
Reiterate what others are saying - the child with a hearing loss may not hear the comments, questions, or answers of others.
Get close - when talking try to be as close as possible to your child. They need to see your face and lips.
Don't hide your mouth - face your child when you are talking and try not to cover your face with your hands.
Allow your child to see your face and expression.
Make sure you have your child's attention before starting - they may only look up and concentrate when your voice gets loud enough, and therefore may have missed the introduction.
Attract attention - make sure you have got your child's attention before you begin to talk, or the first part of the conversation will be lost.
Keep background noise levels to a minimum - turn down the TV when talking to each other.
Try to make sure that only one person talks at a time.
