The other side of Robertson's career since circa 2000 has been Itchy Coo, a publisher of children's books in the Scots language. Initially funded by the Scottish Arts Council, Itchy Coo has proved to be a popular enterprise. Robertson's interest in and use of Scots also features heavily in his poetry and prose, and notably in his first two novels, which blend modern English with Scots. "Katie’s Moose" won the early years category in the Royal Mail Awards for Scottish Children's Books 2007.
