The dry toast rounds are called beschuit, and they're just the local version of a twice baked rusk. A drift to the west of zweiback, if you will. Picture a round a centimeter thick, with a diameter of say 10 cm, very crisp and light. The first baking is as a loaf and then you slice and bake for the second. Since I work mostly with men, I haven't experienced a female colleague having a baby. But the guys all take some time off when their partners have a baby, and on their first day back at work they bring "beschuit met muisjes", simply beschuit spread with margarine and sprinkled with muisjes, pink if it's a girl and blue if it's a boy. It's time to shake hands and acknowlege that your colleague will be sleep deprived for the forseeable future.
