Jerry O'Connell was left red faced after discovering his two-year-old daughter bit another child at school.
The actor, who shares twin daughters with wife Rebecca Romijn, was baffled by his child's poor behaviour and has set out to teach the youngster a lesson.
Appearing on late night TV host Craig Ferguson's U.S. show on Tuesday (05Apr11), O'Connell revealed, "That was a situation... There was a report that the principal gave me that I had to sign... It's a preschool and I had to sign a waiver saying I acknowledge my child bit someone.
"Now I have a book that I read (to the kids) every night called Biting Hurts."
His new album Underneath It All is out now.
