One thing that may help is to mount the floppy with the sync option.
Most people (Mom's) are sufficiently trained to not remove the floppy
while the it is still spinning / light is on.

This isn't clean, of course, and won't help much if Mom really flakes
out and inserts another disk, but it should prevent filesystem
corruption on the first floppy.
