Leighanne Littrell, wife of Backstreet Boys singer Brian Littrell, talks about their son Baylee's medical condition after the six-year-old was hospitalized last week.

"There were a lot of stories going around, a lot of wrong information on what was going on," Leighanne tells OK! magazine. "I had heard stories that his heart had hardened or people thought he had cancer, and I just didn't want it to get so blown up."

"Before being admitted, Baylee had been treated for or thought to have had strep throat, hand, foot, mouth disease and erythema multiforme. After receiving a biopsy, blood tests, an EKG and 2 echocardiograms, Baylee was finally diagnosed with A-Typical Kawasaki Disease," Brian had blogged about his son's condition.

The blog entry went on to explain that Kawasaki Disease causes inflammation in the coronary arteries as well as the walls of the small and medium sized arteries throughout the body. Baylee received a treatment to bring down the inflammation in his coronary arteries and will be closely monitored for the next 6-8 weeks to see if the treatment was effective, according to the singer.

Since his diagnosis, Baylee has been released from the hospital and Leighanne tells OK!: "We've had probably the craziest six days of our entire life and I hope that that's the worst it gets. Baylee's just running around in his Batman costume and he's feeling so much better and his attitude is fantastic."

Leighanne goes on to say that Baylee's improved health is the best Christmas present they have ever received, but the time spent in the hospital didn't leave them much time to shop.

"We're trying to order a Santa because we've been in the hospital for so long," she tells the mag. "We didn't get to shop or anything because we were in the hospital so now we're shopping last-minute for all his family members."
