I feel this, despite not having nearly as much trauma (maybe "yet") as some of the other parents here.
When I signed up my kids at 5ish for AYSO (and little kid clinics before that), my thought process was "they will get some exercise, maybe learn some skills, maybe play in HS like I did, hopefully have some fun". Now it's going on ~8 years later, we're paying ~$6k/yr for my son to play on the second tier team in our city club, driving hours for tournaments (most recently the Vegas Cup), keeping track of all the various leagues/levels and politics (Socal, NPL, EA, ECRL, ECNL, MLSN, MLSN2, etc., as well as the BY/SR thing recently), and thinking about how to evaluate where the "off ramp" is, if/when my kid is unlikely to play past HS. It's a lot more than I anticipated back then, lol.
