We don't know what to do when we see children and young people begging on the street. Are they homeless? Will my money help or will it be spent on drugs? Action for Children work with vulnerable children and young people, homeless and at risk of homelessness, to help them make positive changes in their lives. This is where money we're raising on Byte Night goes http://www.bytenight.org.uk/why/. 

Action for Children https://www.actionforchildren.org.uk/ run a range of
 initiatives to help children and young people. For example, Edinburgh
EASE helps young people in trouble or difficult circumstances to make
positive changes in their lives:  https://www.actionforchildren.org.uk/in-your-area/services/youth-justice/edinburgh-eh1/
