My child finds it difficult to hear when it's really noisy! They can't follow instructions well! I always need to repeat myself, and they keep saying "huh". Their literacy performance at school is quite poor. 

If these are some questions and scenarios weighing on your mind, your child may have Auditory Processing Disorder. 

Auditory Processing Disorder (APD) is a complex disorder which effects many areas of a child’s development, including learning, communication and social development.
