A crazed Brooklyn mom who tried to forcibly abort her cheating hubby's love child by poisoning his mistress cut a deal with prosecutors Wednesday that could have out of prison in less than two years.

Kisha Jones, 40, was seven months pregnant when she tricked Monique Hunter, 26, into taking an abortion-inducing medication on October 2009.

Jones' hubby, Anthony Jones, had knocked up both his wife and mistress around the same time, said defense lawyer Barry Turner.

"My client was in the last trimester of her pregnancy and was acting irrationally," he said outside court.

"I guess her hormones were out of whack."

Turner said accused Hunter of taunting his client,  leaving phone messages with details of her three-year affair - and claiming Jones' man  would soon leave her.

Jones had no criminal history and a life-long record of helping disabled kids, and deserved a break, Turner said.

She was under mounting pressure expecting her fourth child and "she acted in a manner that wasn't consistent with her personality," the lawyer said.

Jones admitted that, using a forged prescription and phone number-disguising software, she called Hunter and got her to take cytotec, causing her to go into early  labor.

She was also accused of then trying to kill the premature newborn in  the maternity ward and later impersonating a hospital exec to try getting the baby off a ventilator -  but those attempted murder charges were dropped.

Wearing a knitted pink hat, the spurned spouse pleaded Wednesday to a lesser charge of second-degree assault.

Prosecutors signed off on the plea deal "after careful consideration and only after talking to the victim in this case many times," assistant district attorney David Klestzick told the judge.

Jones will be sentenced to four years in the klink on Feb. 10 - but with time served and credit for good behavior, she could be out in a year and eight months.

Turner said that Jones and her husband are still married and that Anthony Jones cares for the children and is involved with his wife's legal defense.

It wasn't clear if he has contact with Hunter or her child.

"Everybody's fine," the lawyer said. "The baby is fine, Monique Hunter is fine."
