The stories were widely read by children in schools in the Netherlands until after the Second World War. By then they had become very old-fashioned. The daily life of Ot and Sien seemed to belong to a time long ago in history. Hardly any Dutch children now live in a family with a servant. No Dutch child nowadays goes for a walk dressed in sailor’s costume with a father who wears a cloak and hat. The books are no longer read in schools, but they continue to be popular with Dutch people at home. In 2004, one hundred years after the first book was written, a special exhibition about Ot and Sien was held.
