One shared version as the basis
A schedule becomes active only when both parents approve the same version, including dates, rhythm, handovers and notes. Opening a proposal or remaining silent is never approval.
Review changes transparently
Changing a confirmed schedule creates a new version. Both parents can review, approve or reject it, or respond with a counterproposal.
Keep the confirmed state visible
While a proposal is open, the previous confirmed agreement remains effective and visible in the care calendar.
