Sleep Time (Music Only) Is over Ten Minutes of Lullaby Music to put your Child to sleep. It is the Instrumental version of a the upcoming Sleep time Lullaby. The Modern Lullaby - with meaning. The song version is for people who believe in the power of words sung over a child. If you believe words empower this is for you. The music fades in volume to become a background noise sending the Child to SLEEP. Sleep time is a Billion Smiles Project we put smiles on Parents & Children
