The mom who claims the “girl” she adopted was really a deranged adult dwarf now says the “child” tried to poison her — and boasted about other twisted ways she planned to kill her family.

“She would make statements and draw pictures saying she wanted to kill family members, roll them up in a blanket and put them in the backyard,” Kristine Barnett tearfully told the Daily Mail of Natalia, the 10-year-old she has been charged with abandoning.

“She was standing over people in the middle of the night. You couldn’t go to sleep. We had to hide all the sharp objects,” she said, her story eerily mimicking the plot of the 2009 horror flick “The Orphan.”

Barnett, 43, claims that Natalia had even tried to kill her before she moved to Canada in 2013 without her.

“I saw her putting chemicals, bleach, Windex, something like that, in my coffee and I asked her, ‘What are you doing?'” Barnett told the site.

“She said, ‘I am trying to poison you.'”

The wild case came to light after Barnett and her ex-husband, Michael Barnett, surrendered to authorities last Thursday to be charged with neglect. They were both released on $5,500 bond.

Barnett told the Mail she was suspicious because Natalia was supposedly from Ukraine yet did not have an accent — and did not understand a friend of theirs who could speak Ukrainian.

She says she then noticed the supposedly young girl had full pubic hair and showed signs of menstrual cycles, she told the outlet.

“The media is painting me to be a child abuser but there is no child here,” Barnett insisted.

“Natalia was a woman. She had periods. She had adult teeth.

“The doctors all confirmed she was suffering a severe psychological illness only diagnosed in adults.”

“She was jumping out of moving cars. She was smearing blood on mirrors.”

“She was doing things you could never imagine a little child doing.”
