Build a calm bedtime routine my child will follow

Help me build a bedtime routine for my child that ends the nightly battle. Child's age: [AGE] Current evening: [what happens from dinner to sleep, and roughly when] Target bedtime and wake time: [TIMES] Biggest problem: [e.g. "stalls for an hour", "won't stay in bed", "needs me to lie down with them", "wakes at night"] Household realities: [siblings sharing a room, work schedules, one parent doing bedtime alone] What has already been tried: [WHAT AND WHAT HAPPENED] Give me: 1. A routine of 4-7 steps with approximate times, starting 45-60 minutes before lights out. Keep it the same every night and short enough to do when I'm tired. 2. A simple picture-chart version my child can follow (describe each card in a few words). 3. Scripts for the common stalls ("one more drink", "I'm scared", coming out of the room) that are calm, brief, and consistent. 4. A plan for the first two weeks: what to expect, and how to hold the line without a power struggle. 5. Sleep environment tips (light, screens, noise) that fit my child's age. Keep advice age-appropriate and gentle. If I mention loud snoring, breathing pauses, night terrors that worry me, or sleep problems affecting daytime health, tell me to talk to my child's pediatrician.
