Log

• October 7, 2026: Four planning tools were added: a sleep environment checklist, a printable one-week sleep diary, a bedtime and wake-time planner, and a questions-for-your-doctor checklist. Each names its sources and states that it is general information, not medical advice.
• October 7, 2026: The Tools page was rewritten so that it lists only these tools, and the Start here page was refreshed to point to them and to the main guides.
• October 7, 2026: The About page was updated to point to the contact form and to the how-we-check page.
