A passion project from Scott Hanselman

Baby Smash! was created in 2008 so Scott’s kids could explore the keyboard safely. Inspired by the Mac classic AlphaBaby, it keeps computers secure while delivering instant joy.

The app locks down the Windows key, Ctrl+Esc, and Alt+Tab so nothing important gets closed. Parents can exit anytime with Alt + F4 or open options with Shift + Ctrl + Alt + O. Baby Smash! remains free, open to community feedback, and continually refreshed with love from the Hanselman family.
