It’s Sleep Week at Mammalingo. (A theme! It was either this, or Rainbows and Unicorns Week. And, yes, there was a coin toss.) I welcome your words, definitions, essays, haikus, and half-baked thoughts about sleep, sleep training, sleep deprivation and sleep schedules. If you have anything to say at all that pertains to sleep, send it on over to mammalingo@gmail.com.
