Polish nursery rhyme 

With the lullaby, children sleep a long time, and their sleep is long and uninterrupted. Lullabies have a very positive effect on the baby. They incredibly simulate his imagination. By listening to lullabies, both hemispheres of the baby's brain develop, especially when the lullaby contains both melodies and words. One part of the brain develops through the melody heard and the words of the lullaby. The child's brain then works more intensively and both hemispheres work.

A spark's blinking

A spark's blinking is an old polish nursery sing by grandmothers to their children in Poland. It is great as a lullaby to make children sleep. This melody lulled millions of Polish children to sleep when their mothers and grandmothers hummed it. We present you this melody that sounds like it is from a music box.
