establishing timeout

My LO is 16 months. I do home daycare so I am home with her all the time with her. She is becoming mean and hits. She will squeal if she doesn't get a toy she wants. Doesn't listen to simple commands. We need to start establishing a time out, but I don't want her crib to be a "scary place" where she thinks she's in trouble when I put her to bed. Any recommendations?!
