Rising demand for kinship care services in Dumfries and Galloway is putting social work budgets under pressure, councillors have been told.
A report to the local authority has estimated an overspend of £173,000 on the service this financial year.
Kinship carers are relatives or friends who look after children who cannot be cared for by their own parents.
The service is seeing approximately five new cases a month, with an annual cost of £4,300 per placement.
Officials say the budget had already been increased for 2013/14, but the volume of cases is beyond that anticipated - hence the estimated overspend.
A review of the scheme is being brought forward to ensure that while it fully meets care policy, the cost is affordable on a sustained basis.
