What is a foster sibling?

A foster sibling is a term that's often used to describe the relationship between children living within foster families. The household may have biological or adopted children of the foster carers living alongside brothers and sisters from the same family who are cared for children. Foster siblings can often build strong bonds and one thing we hear from foster carers over and over again is that their own children have grown up to be more empathetic as a result of being a foster sibling.
