+                    Wir planen ein weihnachtliches Programm mit Geschichten, Liedern, Essen und der einen oder anderen Überraschung. Falls du ein Instrument spielst, bring es auch gerne mit.

+
+                    Getränke, insbesondere Glühwein, Kinderpunsch und Ähnliches, wird von uns organisiert.

+                    Bitte informiere uns kurz, was du gerne mitbringen würdest, damit wir besser kalkulieren können.
+                    Ansonsten darfst du auch sehr gerne Plätzchen, Weihnachtsdeko oder Ähnliches mitbringen.
