That Sound

I hear a sound so beautiful
Sometimes it's loud other times so sweet and soft,
In the mornings it makes me want to scream with its wining,
In the afternoon I am straining to hear the sound but its not there
By late afternoon I am so excited to hear that sound again telling me
all about its day.
Through out the evening the sound is louder and louder but than
it gets softer and sweeter until all I hear is silence.
That's when I enjoy the sweetest sound , my precious children sleeping.
