Hello, welcome to Healthcaremagic. Enlarged adenoids
can lead to difficulty in breathing in children by blocking the nasal airway. The adenoid usually reaches its greatest size by about age 5 years or so, and then fades away by late childhood - generally by the age of 7 years. In some cases when adenoids are large enough to cause difficulty in breathing to large extent they can be removed. You must talk to your doctor and cosult about it. It can be decided only by examining the child and seeing its affects on health. Wish your child good health.
