    “There's a mother in PICU(儿童重症监护病房)who wants to talk about a kit she received,” the nurse told me. “Something about it made her cry.”

    I've been a child-1ife specialist at the Cleveland Clinic Children's Hospital since 2000. I help families understand diagnoses and treatment plans and manage the ups and downs that come with caring for a sick child. Tough talks with parents are part of the job, which still makes me feel nervous.

    The kits the nurse was talking about were something I had recently introduced to the hospital: Comfort Kits from Guideposts. They were supposed to make a child's experience here easier, not upsetting.

    When I came across the kits at a conference. I fell in love with them. A treasure box of items designed not only to entertain kids, but to comfort and inspire them. There's a coloring book, a stress ball, a CD of relaxing music, a hairy star named Sparkle, a journal and much more. I really believed these kits would help kids. I wished I hadn't been mistaken.

    At the patient's room in PICU I saw a little girl, sleeping soundly, surrounded by tubes and machines. My eyes met her mother's. The kit was open on her lap and tears were running down her cheeks.

    “I'm Shannon. I manage the Child Life Department.” I said. “I'm sorry if the kit upset you .It's a new item…”

    The mother shook her head. “This has been one of the worst days of my life .I felt so scared and alone. Then I was handed this box. I know it's for my daughter, but it's just the comfort I needed. I wanted to say thank you.”

    With that I knew Comfort Kits belonged here. We've been using them for almost three years now. Each child who's admitted to the hospital receives one. Every day I see kids coloring, journaling, playing with Sparkle.

    But as this mom showed me Comfort Kits aren't just for kids. The hope they bring, which can be in short supply in hospitals sometimes, is felt by the whole family.

    I like travelling very much.____They are wonderful adventures filled with new sights and experiences. And my wife and I have another trip in the planning stages.

    We're home now and have settled back into our daily routine of life.____ I find that when I am at home, particularly for a while when we have just returned from a trip, I feel very comfortable. Perhaps it is because everything around me is familiar and the daily routine is so much the same and I can move through it almost without thinking.____Perhaps it is because we can have meals at home instead of always being in restaurants, although it's nice to let someone else do the cooking, and because I can sleep in my own bed. There are times I think it would be nice to simply stop travelling and stay home.____

    Yet I guess I am probably a restless soul because I know that after I have been home for a while I will start to think about other places we might go and other things we want to see.____ We will travel again and we feel fortunate to be able to do so.
