Dutch police have been continuing to search a house after the bodies of four babies were found in suitcases in the attic.
A 25-year-old woman believed to be their mother has been arrested on suspicion of killing them.
The authorities say the babies are thought to have been born between 2002 and this year.
An inquiry is underway into the cause of the deaths.
The gruesome discovery has shocked the local community.
One woman in the area said she cried when she read about it. For such a thing to happen several times could not be an accident, she said.
Last month a woman was arrested in northern France after the remains of eight newborn babies were found.
This new case of suspected infanticide took place in a village in the Dutch province of Friesland.
Police were tipped off after the woman was seen to be pregnant several times without ever having any children.
She reportedly said she gave up the babies for adoption, but could not produce any documents. She then admitted putting them in the attic.
