First, I have been a camp counselor in four different camps in Germany. I made my first summercamp experience with the "Zeltlagergruppe St. Maternus Breberen/Schümm, an organization funded by the katholic church. They organize a two-week summer camp every year and I partook several years as a child before becoming a counselor myself. They are a small organization with little to no hierarchies and the working environment is one of actively looking for tasks to do, so there I helped organizing, cooking and taking care of the participating children by offering different games and an open ear for their problems. I also halped organize and execute a german language camp with the "SJD - Die Falken" an orgnaization funded by the SPD, one of the main political parties in Germany.
Other experiences of working with children include after school tutoring, my current job as a teaching assistant and a year of working at a children's home where I helped the children with their homework and took care of them during their free time. What I enjoy the most while working with children is just making the smile or helping them overcome their fear and try something new. And I love the moments where you can see that a child is making some sort of progress, whether that is to try out food he/she does not know or he/she keeps himself/herself from hitting someone who has insulted him/her or just a simple "thank you" when being offered juice.
A challenge I have faced multiple times throughout my different experiences with children is to find a balance between being nice and allowing and exerting authority and keeping the rules. I tend towards being too nice and allowing but in my experience patience and not rushing decisions are great tools to fing the right balance again.
