She was supposed to board a plane today and fly to Disney World in Florida, where she was looking forward to meeting Cinderella and visiting her magical castle.

But those plans were derailed when Alpers' Disease struck with a vengeance, sending three-year-old Morgan Gain back to the hospital, where she remains in a medically-induced coma.

"The doctors are telling us that it doesn't look good," Morgan's mother, Dasa, said Wednesday. "We are going to keep (her in a coma) for five more days, but they are not giving us much hope that she will come out of this."

For Dasa, the scene is horrifyingly reminiscent. Earlier this year, Dasa spent every waking moment by her oldest daughter Mikayla's side while she battled Alpers' Disease, a rare, progressive neurodegenerative disease of the brain that occurs in infants and children. The disease affects less than 200,000 people in the U.S., according to the National Institute of Health.

But for the Gain family, the deadly disease has struck twice.

In March, Mikayla died from complications associated with Alpers' Disease, and now young Morgan is battling to stay alive.

Dasa's youngest daughter, Madison, has undergone genetic testing and is the only one of the three girls who does not have the disease.

Despite facing the unthinkable - losing a second child within a year - Dasa is praying for a miracle and asking for prayers.

"Her father and I appreciate all the friends and people who continue to pray for Morgan and all of us," Dasa said.
