The wife of cannibal cop Gilberto Valle got back to regular life yesterday — spotted at a Reno, Nev., children’s play space with their infant daughter two days after her husband was convicted in a scheme to kill and eat women.

Kathleen Mangan-Valle seemed in high spirits during the hourlong session at a Gymboree play center.

Mangan-Valle took the witness stand against Valle last month and recounted how she discovered that he planned to devour her, along with other women.

Mangan-Valle tipped feds to her NYPD husband’s perverted plot after finding links to disturbing Web sites on her computer.
