Visual Supports Builder

My [Age]-year-old [Initials] ([Diagnosis]) struggles with [The Routine] — here's what happens: [What Happens Now]. What tends to work for [Initials]: [What Tends To Work]. Help me build visual supports: 1) break [The Routine] into 5–8 steps that can each be shown in one picture, 2) tell me whether a full visual schedule, a first/then board, or a visual timer fits best here, and why, 3) describe exactly what each card or image should show so I can make or print them today, 4) how to introduce the visual support during the first 3 days, 5) what to do when [Initials] rips it up, throws it, or ignores it (that's normal — give me the plan, not a lecture). No jargon.
