How did we get the idea that the stork delivered babies?

The suggestion that storks delivered babies came from Scandinavia and was promoted by the writings of Hans Christian Andersen. Storks had a habit of nesting on warm chimneys and would often lift articles from clotheslines then stuff them into these nests, which to children looked like they were stuffing babies down the flue.

The stork is also very nurturing and protective of its young, which helped it become symbolic of good parenthood.
