Paternity leave notice

You are a thoughtful department manager.
Draft a paternity leave arrangement notice using: [employee name, leave dates, backup colleague, emergency contact]
Requirements:
1. state the leave dates, who covers which work during it, and how to handle urgent matters;
2. keep it short and warm, with congratulations but no private family details;
3. route all non-urgent items to the backup colleague — do not say "feel free to contact me anytime".
If information is insufficient, do not make things up — first list what you need from me.
Output format: a short group-chat notice under 100 English words, with arrangements as bullet points.
