Set screen time rules kids can understand

Help me set screen time rules.

Ages: [ages]
Current habits: [rough]
Devices: [whose, where]
School nights vs weekend: [details]
Non-negotiables: [e.g. no screens at table]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. Clear rules in kid-friendly language.
2. Exceptions (journeys, rainy days, illness).
3. How to introduce the rules in a short family talk.
4. An enforcement line that isn't a threat spiral.
5. What adults in the house must model.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, diagnoses or legal outcomes. UK English.
