What is a typical Dutch tradition when a baby is born?

When a baby is born in the Netherlands, the typical traditional Dutch snack you can expect to be served when visiting the proud new parents is "Beschuit met muisjes". It consists of beschuit, which is a round, toasted, dry, and crunchy rusk,  smeared butter, covered in "muisjes" (literal translation is little mice), which are sugar-coated aniseeds. The colour of the mice will pink if the baby is a girl, and blue for a boy.
