In homes and schools around Bosnia, young people this December have been preparing gift boxes they hope will put a smile on the faces of their peers living through war in Ukraine - as such presents did for many of their parents a generation ago.

Responding to an appeal launched by a small Sarajevo museum, hundreds of Bosnian children have been filling small boxes with warm clothes, toys, candies and other simple gifts to be delivered to the children of Ukraine in time for the New Year.

For parents and educators who are helping them select what to send, the experience has awakened rare happy memories from the time when they were on the receiving end of the kindness of strangers while growing up in constant fear of death.
