Witnesses say 37-year-old Yvonne Holmes was visiting children at a home on Highway W when she became "delusional" and took out a butcher knife and started stabbing the children.
She then stabbed herself.
She died at the scene.
The children, ages 2 and 12, were seriously injured, but are expected to survive.
A 38-year old man was stabbed trying to protect the children.
He was treated at the scene.
