Babysitters/childminders can be arranged by parents with the hotel, at a cost of around 10 euros per hour during the daytime and 12 euros per hour in the evenings. Those interested can contact the conference agency at, although any resulting arrangement will be between parents and the hotel or the babysitters, not with the agency or the conference organization. 

Another option is to request support from the LSST-DA through their Childcare Grants.
