She’s charged with plotting to kill her kid’s father — but NYPD cop Valerie Cincinelli says her son still needs his mother.

Cincinelli — who is accused of plotting to arrange a hit on her estranged husband, Isaiah Carvalho Jr., and her boyfriend’s teen daughter — was hauled to divorce court Thursday to ask a judge to let her have phone contact with her 5-year-old son.

“The longer he has no contact with his mother the longer the chances he’ll be alienated from her,” her lawyer, Vincent Trimarco, argued in a brief matrimonial court hearing in Mineola.

Contact was stopped in July after a court-appointed psychologist complained she was flouting phone call rules and getting argumentative.

“It was almost amusing to hear her attorney say that the child will be alienated from his mother when she thought nothing of depriving the child of having a father,” Carvalho’s lawyer, Erika Sakol, told The Post after the hearing.

Carvalho is fighting to keep Cincinelli from contacting their kid from jail in Brooklyn. The Oceanside mom remains held in lieu of bail since a court-ordered psychiatric report found she suffered a “lack of impulse control” and “defensiveness.”

Judge Jeffrey Goodstein said Thursday there will be no change in the no-contact order until the psychiatric evaluation can be unsealed for his review, and the kid gets evaluated by a therapist.

The parties are due back in court Oct. 4 for an update.
