The rule in all states that have heard such actions is that an unemancipated child cannot sue his parent for a negligent tort in their ordinary family relationships. There does not appear to be any exception to that rule, unless the "business injury" rule (discussed below) is an exception. It is the opinion of this writer that this iron rule is archaic and should be changed. A total stranger may recover damages for the negligent act of a person who may be a parent, yet that same parent's own child may not recover.
