Charlie has Cystic Fibrosis (CF) and goes to the hospital frequently. One of his parents has CF and at a young age, he had symptoms. He goes to a specialized hospital for treatment when needed, at least every three months he sees a doctor. 
One day in the morning, Charlie wakes up with chest pain, he has a bit of difficulty breathing. He does not want to go to the hospital, so he doesn’t tell his parents about it. His parents immediately recognize the symptoms and they drive him to the hospital.
During the ride towards the hospital, Charlie is thinking about the last time he visited the hospital, this makes him afraid because he is thinking about all those tubes which went inside him during that visit. Arriving at the hospital, Charlie stays close to his parents. While walking to the waiting room, he sees those nice playing blocks, where he had so much fun last time. Other children are playing with the blocks and Charlie is currently a bit shy, so he stays with his parents. While waiting, the parents give Charlie a phone to play with. They recognize that Charlie is very withdrawn, playing with the phone should distract him and therefore improve the waiting time. Other children around the hospital are all playing, but Charlie doesn’t have the urge to join them. 
During an inspection, the doctor comes inside the room with a present. The doctor, Charlie, and the parents start playing with the toy, after a few moments, Charlie joins in the play. The doctor asks the parents, without Charlie noticing it, to continue the play with Charlie. First, the doctor does some motoric tests based on plays with Charlie. Continuously the doctor does some inspections while Charlie is distracted by play. 
The doctor notices some growths in the nose (nasal polyps). Because those are rare for children, and Charlie already had some bad signs, the doctor immediately wants to operate. While preparing for Chirurgie, Charlie and his parents went to a pedagogical expert. This expert tries to explain and prepare what is going to happen. Through the explanation, the expert noticed that Charlie became more and more afraid. Through playing with the tools of the operating room, the pedagogical expert tries to animate in a fun way what is going to happen. Charlie was calmed down by that and the parents were somehow relieved to see that. This way of communication was also clear for the parents in such a stressful situation. 
Children are always brought under anesthesia, during the removal of nasal polyps. This was a good thing because Charlie was very nervous and then he could sleep during the operation. The operation was very short, and within a matter of time, Charlie woke up in his bed in the hospital. The parents called the pedagogical expert back to give further information. While Charlie was still somewhat confused waking up, the expert came inside the room with coloured clothes. The coloured clothes instead of white clothes were an indication for Charlie, that he did not have to expect another operation right away. The pedagogical expert gave Charlie his present, which he had before, back. Through the reaction of Charlie, which was no tremendous reaction at all, the expert noticed that Charlie was not feeling well. Through a conversation with the parents alone, the expert said that Charlie should stay for two days. That day, Charlie stayed in bed, not wanting to do anything because he was exhausted and a bit confused because of the resulting pain of the operation.
After waking up the next day, Charlie felt a lot better. He was still a bit tired, but after lunch, he asked if he was allowed to go outside of bed. First Charlie stayed in his room, playing with his own toys. After a few moments, he sneaked outside his room to play with other kids. The pedagogical expert saw this and observed Charlie for a few moments. Charlie was not fully recovered yet, but he showed initiative. Charlie was still playing when the parents came to visit. The pedagogical expert received the parents and showed that it was a good sign to see Charlie play again.
