Charity Sue's Place in Newark had its lottery grant turned down earlier this year and staff are now using cash reserves which will soon run out to continue their services for children who have lost a parent.
Six year old Jonathan never knew his dad Mark who died when he was just a few months old, but his mum Lorraine from Nottingham has made sure he knows all about him.
The charity runs a play centre where youngsters and their parents can talk to support workers about their bereavement and get help to deal with any emotional problems. Last year it helped almost 300 families.
It was when he started school and was talking to classmates about their fathers that Jonathan started showing signs he might need help. His mother brought him to Sue's Place in Newark.
After eight weeks of play therapy, Jonathan's mother says that he has calmed down and started to concentrate at school and enjoy life.
Staff are now looking for other funding sources to help a future generation of children.
