A woman has demanded compensation from health authorities in northern Spain after discovering she was mistakenly swapped at birth with another baby 19 years ago, local reports say.
The woman was mixed up with a baby who was born on the same day in 2002 at a hospital in Logroño, south of Bilbao.
Both babies were put in incubators before being handed to the wrong parents.
A regional government has acknowledged the mix-up, blaming "human error".
On Tuesday the health minister for the government of La Rioja, Sara Alba, said it was not possible to conclude who had made the mistake.
She said it would "be impossible for something like this to happen again today" because procedures for identifying babies were "safe and reliable".
