Private by default
Each family sees only the updates meant for them. There is no shared group feed across the children a nanny works with.
Reassurance without hovering
The feed answers the practical questions: last bottle, current nap, notes for pickup. The nanny doesn't have to send a separate update.
Shared with helpers, not parents
If a nanny works with a helper or co-sitter, the care log stays in one place. Every entry shows who logged it.
