Your first weekly parent sync
The first weekly meeting for the two of you is Quick Sync. It takes about 20 minutes.
Open Rhythms and press Start meeting on the Quick Sync card. The first time, that card is not on Rhythms yet. The card in the center of Home says Start this week's Quick Sync. It creates the meeting and opens it. Rhythms is one list, with no tabs.
In the meeting, share a win, name one thing you appreciate, listen without fixing, pick one issue to talk through, and agree on next week. Check each step as you go, then finish.
When you want the longer hour, add Weekly Parent Sync from Templates. Quick Sync moves to Inactive, and the notes from those meetings stay.
