Baby Sleep Tools Calculators

What it does

You're awake at 3 AM. Your baby won't sleep. You're Googling frantically, finding contradictory advice from strangers on the internet. Some say let them cry. Others say never let them cry. Some say the wake window is 45 minutes. Others say 2 hours. What you actually need: A calculator that knows your baby's age. A guide grounded in pediatric sleep research. No email walls. No fake urgency. No fake sleep coach credentials. That's Baby Sleep Tools.

Free science-backed baby sleep calculators, wake window charts, nap schedules, and month-by-month guides. Built for tired parents at 3 AM.

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
