Children's Commissioner Keith Towler will today visit Noah's Ark Children's Hospital for Wales to unveil an art exhibition depicting young patients' experiences of hospital.
The youngsters have worked alongside artists from Valley and Vale Community Arts for the project, which is funded by the Arts Council of Wales.
Many patients have long-term conditions which make them frequent visitors to the children's hospital.
Through the project, they turned to paint and pencils to share their their emotions as they went through treatment.
Linda Hughes-Jones, who works for Cardiff and Vale University Health Board and also led the project, said the artwork is 'eye-opening' and has given health workers 'a different perspective' on how it feels to be a young person in hospital.
The artwork will be displayed on the hospital walls, as well as appearing in a short DVD.
A Wales-wide research project aimed at finding out how children use the internet and digital media is being launched today.
Children's Commissioner for Wales Keith Towler will meet pupils in the Vale of Glamorgan as part of the project launch, which coincides with Safer Internet Day.
Cadoxton Primary School, Ashgrove School, Barry Island Primary School and Ysgol Gyfun Bro Morgannwg are currently taking part in a pilot of the Welsh Government's new digital learning platform, named 'Hwb'.
During the visit, the commissioner and members of Wales' National Council for Digital Learning will find out how pupils stay safe online and whether enough is being done to help them use the internet safely.
The Children's Commissioner for Wales has published the 'Missing Voices' report, pointing out that local authorities must provide an independent professional 'voice' for looked-after children and young people, care leavers and children in need - but that many young people aren't aware of the right.
