Summary Cathy and Richard, both 34, are hoping to adopt a sibling for their daughter Rachel, who was conceived after fertility treatment. After five years of trying unsuccessfully for a second child, they've decided to adopt. They think they want a toddler, but have enrolled on a project designed to encourage them to consider adopting older children who - unlike the little cute toddlers - sometimes struggle to find homes.

David Akinsanya arranges for Cathy and Richard to spend some time with siblings to find out if they could cope as a family of five. They decide they could adopt more than one child after all, but their social worker has concerns about whether their daughter Rachel could cope with a new adopted child in the family. Eventually, the family are matched with a child with a possible disability. David sets out to help the couple decide whether or not they could cope with the needs of a disabled child.
