The collection has been reprinted many times and has become one of the most beloved children's works of the 19th century. Written from the perspective of a child, the poems cover a wide range of themes, from bedtime and playtime to nature and adventure. Here's an excerpt from one of the featured poems, 'The Unseen Playmate': "When children are playing alone on the green / In comes the playmate that never was seen / When children are happy and lonely and good / The Friend of the Children comes out of the wood."
