Soccer. Baseball. School. Repeat.
The school sends a feed. Soccer sends a feed. Then baseball, football, volleyball, softball, band, swim, picture day… and somehow every family member is supposed to add all of them to Google Calendar. Again.
Add soccer to Mom. Add soccer to Dad. Add soccer to Grandma. Repeat for baseball, football, school, volleyball, softball…
Miss one update and someone is late to the tournament.
