These twin boys have a hunger no meal plan can satisfy.

Stevie and Eddie Ahern, 12, were born with a rare combination of autism and Prader-Willi Syndrome, a condition that causes an insatiable appetite. That means the boys, who live in New Haven, Conn., will devour just about anything.

“They can never feel full, so they could potentially eat themselves to death,” their mother, Dianna Schatzlein-Ahern, told Barcroft. “I even have to lock up all of the medications in my room, then lock the bedroom door once I’m going to sleep.”

She also padlocks the refrigerator and even the broom closet to be sure the kids don’t make dinner out of the cleaning supplies.

The demands of raising Stevie and Eddie — like strictly monitoring their 1,200 calories-per-day diet — proved too strenuous on Dianna’s relationship with their father. He lives elsewhere with the couple’s other two children.

“I’ve been living with just the boys for two years now,” she said. “I still see my other two children, but it’s hard being away from them.”

Another problematic effect of the disease is the boys’ violent outbursts, which have become difficult for the loving mom to control.

“Stevie can be very violent, he will just pop and start knocking things over,” Dianna said. “He goes after Eddie all the time. I just say ‘Eddie, go in mommy’s room and wait’, but it can take hours for him to come out of it.”

“I try to explain to them that they will be taken away from me, that they’ll have to go to a hospital, but they’re not able to understand,” she added.

Nonetheless, Dianna says she must stay strong for the sake of her food-loving pre-teens.

“I really don’t know how I cope. It’s taxing, but I can’t have a nervous breakdown because I’m all they have.”

“They’re such good kids, they’re very loving to me and I love them so much,” she said.

“I’ll keep fighting for them as long as I can.”
