A 4-year-old Massachusetts boy is being called a hero for dialing 911 when his mother had a seizure.

Harwich resident Ashley Fontaine suffers from regular seizures, so she and her husband taught her son, Matthew, to call for help if she's incapacitated.

Fontaine was getting ready for work one day last week when she had the seizure. The boy grabbed her cellphone and called 911. He stayed on the line with dispatchers until help arrived.

Fontaine told WHDH-TV that Matthew is her "little hero."
