Funded by the German Research Foundation (DFG) through the research group 2692, there is a parent-child room available on E5 that can be used for childcare emergencies. The room has Tripp-Trapp chairs, a table, a sofa, children's toys, and audiobooks. Of course, there are also physical toys available, but these are reserved for the kids ;-)
The room can also be used by parents from other research groups. Please get in touch with Jürgen Schnack beforehand.
