This 4-year-old is best friends with the man who cleaned his hospital room

(CNN)The friends first met a year ago when 4-year-old Cooper Baltzell was driving a toy car down the hospital corridor, handing out candy to the staff.

It was during one of Cooper's many hospital stays for Hirschsprung disease, a rare, inherited condition affecting the body's digestive system.
That's when he bumped into 57-year-old Gregory Watson, a housekeeper at the facility.
"I was doing a discharge and he goes, 'Sir do you want some candy?' I'm like 'Oh yes!'" recalled Watson.
    You see Cooper is kind of like the mayor of the fifth floor during his stays at the University of Minnesota Masonic Children's Hospital
    The little boy quickly connected with the man. This is the story of how the pair became best friends.

    The beginnings of a friendship

    Watson cleaned Cooper's room every day during his stays. Their friendship grew.
    "Cooper would be really bummed when Gregory wasn't there and somebody else was cleaning the room," Cooper's mom Ashley Baltzell said.
    "Gregory is also a chatty guy. It's kind of a match made in heaven."
    The hospital housekeeper feels it's part of his job to be friendly to the families and the children who sometimes have to endure painful procedures during their stays.
