Children don’t often know if they are having difficulty hearing, and it is not always possible to tell if your child can hear all sounds just by watching what they do.

Developmental milestones are helpful to monitor how your child’s hearing is developing as they grow. You can use this list to help you decide if you need to talk to a health care professional about your child’s hearing. The only way to know if your child has a permanent hearing loss is by having their hearing tested.
