Last year was the worst yet for Syria's rising generation, with at least 652 children killed in 2016, the United Nations' child relief agency has said.
To mark the 6th anniversary of the war in Syria, UNICEF have released 'Song for Syria', which is performed by a 10-year-old girl who was born blind.
The video was filmed in a war-ravaged part of Syria where many children have lost their lives.
At least 255 children were killed in or near schools last year and 1.7 million youngsters are out of school, Unicef said.
The song is a "message of hope" from Syria's children, with the lyrics saying they want their childhood back.
Six years ago, in 2011, Syrians protested against President Bashar Assad's rule.
The uprising, which was part of the Arab Spring movements across the Middle East, quickly escalated into full-blown civil war.
Children were among the first victims of the government's brutal crackdown.
Around five million people remain trapped in areas of active fighting, including almost one million in besieged areas who have no access to sustained humanitarian assistance.
