I would start by agreeing the plan with the family rather than asking the coaches to become medical experts.
The player should be included in football normally, with the adults understanding only the information they genuinely need to keep the child safe.
That means clarity on what the family’s established plan is, where any necessary medication or equipment is, what signs require action and who is contacted.
If the coaches are being asked to do something they do not understand or are not trained to do, that needs resolving before the session — not guessed at during an emergency.
The aim is not to make the child feel medically supervised every minute.
It is to make the safety arrangements predictable enough that everyone can concentrate on football.
A good plan usually reduces anxiety for the coach and the family because responsibilities are clear.
For medical decisions, follow the family’s professional medical guidance rather than inventing football-specific rules.
