Otitis Media or Hearing loss in children can be common.
Otitis Media is the inflammation of and a build-up of fluid in the middle ear, often called glue-ear. When the fluid is present in the ear it makes hearing very difficult for the child, making speech sound muffled.
It’s difficult for children to learn effectively when they hear muffled speech as listening to people is how they form their own words. There may be no pain associated with Otitis Media so it’s important to look out for signs of not hearing, needing the TV louder or inattentiveness.
If you have any concerns you should contact your doctor in the first instance.
