It finally happened so I thought I'd share.
Yesterday I had the finest D&D experience I have ever had. My 10 year old daughter got behind the DM screen.
It has been a couple weeks in the making. In the last couple of days she has had lots of questions about monster stat blocks, how she should handle this or that situation etc etc but she managed to design and run a six encounter delve for 5 1st level chars.
Her first D&D experience was 2 years ago when I took them through Kobold Hall in the back of the DMG. This was her inspiration for her first DM session, but with her own twist. The BBEG was a young white dragon, but she had two opposing forces of goblins and kobolds each trying to prove they love it more!!!
The party roster was
- Goliath Earth Warden (played by me),
- Dragonborn Dragon Sorcerer (played by my son),
- Human Laser Cleric (played by my wife)
- Halfling AD Rogue (also played by me) and a
- Deva Orbizard (that she controled)
As to be expected her narration and description were a little nervous a first but she quickly got into her stride. She included difficult terrain, skills, puzzles and a small sub-plot, a kobold wanting to get out (a la Splug).
All things considered she did
really well and right now I am the happiest father in the world and I can't wait for her next outing as DM.

Ps. She also cleared up a disagreement that has appeared several times on these boards. According to her Drow MUST be pronounced as in cow NOT blow.
