Adding an event

1. Open Calendar and choose a day.
2. Give the event a title, a date and a time — or tick all day.
3. Optionally link it to one child, and add a place and notes.
4. Save. Your co-parent sees it immediately.

Every event is part of the family record, so there's no argument later about when it was added or by whom.

Adding something to the calendar is not the same as agreeing it. If it affects your co-parent's time, say so in Messages as well.
