These little sounds make me melt. My cat has been more chatty lately, and makes tiny contented sounds in her sleep. I'm also remembering when my ds's were babies, and those cute little sighs and sounds they made after they were all fed and sleeping. Even my bf just made a sweet little sound in his sleep (don't throw up). Horses sighing and relaxing when eating hay, dogs in their sleep ... It doesn't matter. These tiny little sounds are the sounds I love.
