TORONTO -- The parents of Baby Kaylee are banned from visiting their daughter without supervision at the Hospital for Sick Children where they were picketing yesterday to get an MRI for their child.

Jason Wallace and Chrystal Vitelli, who's pregnant with a second child, were wearing signs slamming the world-renowned hospital. Some signs were taped to chairs they brought to one of the hospital's entrances on Elizabeth St.

"We are not leaving until Kaylee gets an MRI," Wallace said. "We are her parents and we want the best for our child."

The family wants an MRI procedure done to help determine the cause of seizures she suffers but doctors say it's too risky for the girl, since the procedure would require anesthesia.

"We are so frustrated that we can't express our feelings," Wallace said. "We can't even go in and see her."

However, Vitelli said she was allowed to see Kaylee Wednesday night, adding, "They said we have to be escorted to see our daughter."

Kaylee, from Bradford, has been at the hospital for about a month undergoing tests. She suffers from Joubert syndrome, an extremely rare brain abnormality that could cause her to stop breathing during sleep.

Wallace was the outspoken man at the centre of a media storm in April after offering his ailing daughter's heart, if she should die, to the family of a baby girl in desperate need of a transplant. After Kaylee was removed from her respirator, she survived and the transplant was cancelled.

Hospital security officials were keeping an eye on the couple as they picketed.

As they walked, hospital officials called Wallace to report Kaylee had to undergo a CT scan. He looked physically upset.

Hospital spokesman Matet Nebres said: "The hospital always acts in the best interest of the child."

Wallace this month appeared in court on charges of aggravated assault and robbery. A trial on those charges is expected this fall.
