Welsh winger, George North, is visiting the children's cancer ward in Wales for the first time since becoming ambassador for LATCH earlier this year.
The 19-year-old will meet the children there and also donate a signed Welsh rugby shirt to the charity.
North was announced as the ambassador at the charity's 30th birthday, but he couldn't attend due to his rugby commitments.
LATCH supports children with leukaemia and their families in Wales.
