As a leader you can only treat what you know about. Also I would not be too concerned about the antibiotics. That may be a CYA by the ER.
Could be a good learning experience for the troop that all injuries need to be reported to the leaders so proper care can be provided. That's why we have the big honking medical kit (smaller one for backpacking) on all outings
That's okay. He can content himself with knowing that he's the kind of clergyman who would refuse to help a young parishioner as he grew up to find the cure for cancer leading to his earning the Nobel Prize.
Did he go home early or were you with him last year? I ask because only twice have I seen anxiety like what you are describing with a 2nd year, or later, camper. First time was a camper who left early his first summer. Long story short camp was literally down the road from mom, mail made him homesick, and she picked him up Wednesday, we had a chat with mom about the letters and about not picking him up the 2nd year. Yes, he was severely homesick, but he made it through.
The second instance was more complicated. This was an 18 year old camp staffer working staff for the first time. Dad was his SM and they did everything together: camp outs, summer camp as a camper, even a HA trip. Outside of Scouting, whenever he did out of town sports trips, dad went with him, although dad was doing his own thing. Long story short, Staffing camp was the first time he was away from dad ever. He did OK the first year, and is working camp again.
I see this all summer long! I work at a Boy Scout camp in the first year scout program so I’m working with be youngest in camp. I don’t want you to think that this isn’t atypical.
I’m not entirely sure how a Cub Scout summer camp works, but I’m assuming it’s somewhat structured like a Boy Scout one. Have your leaders tell the staff that he interacts with throughout the day. They can help keep him engaged and keep his mind off home. This usually works for scouts I work with. Small tasks such as getting something for me, holding something, has a huge impact on them since it makes them feel more needed and that they belong there.
Staff at camps are usually pretty good about dealing with homesickness.
