Mike Beese and his wife Jo from Pontypridd have been fostering for a year. Mike believes foster carers should be recognised as a professional workforce.
"There are a lot of roles we have to fulfil - teacher, nutritionalist, psychologist," he told ITV Wales.
"There is training available - but I think the Welsh Government has to advertise the fact that support is there to encourage more foster carers."
The Fostering Network Wales says an 'urgent overhaul' is needed to prevent children being needlessly moved around the system.
Its report, published today, says the number of fostered children in Wales is at an all-time high, with at least 550 more foster carers needed in the next 12 months for the system to be able to cope.
The Welsh Government says it is committed to supporting foster carers in Wales, but has welcomed the report.
