The National Deaf Children's Society has provided a free guide to help parents of children with glue ear. Glue ear, which occurs when the middle ear becomes blocked with fluid, is one of the most common childhood illnesses, affecting 80% of children under 10. The guide includes information on the signs and symptoms of glue ear, potential causes, treatment options such as grommets or hearing aids, and how to seek help from a GP. By providing this resource, the charity aims to help parents better understand and support children experiencing temporary deafness and other effects from glue ear.
