(HealthDayNews) -- Many young kids stutter as they learn to talk, so if your two-year-old is stumbling and hesitating over his words, don't panic.

Stuttering is fairly common among 2- to 5-year olds, according to Massachusetts General Hospital, so don't aggravate the issue by correcting or interrupting your child.

However, stuttering may be a concern if:

• It persists for more than three months.
• It's accompanied by signs of frustration, such as fist clenching.
• There is a family history of stuttering.

In this case, your child may benefit from a speech evaluation, followed by speech therapy if needed.
