In this paper we present a case study on the informal practices of families with small children, before and after the emergence of the COVID-19 pandemic, in Vasco da Gama Garden, an urban park located in the Belém neighborhood in Lisbon, Portugal, which is highly touristic, commercial and increasingly gentrified. Based on an ethnographic approach that included field observation, formal interviews and informal conversations with park frequenters, the findings presented here are discussed in terms of the relationship between the pandemic, urban public places, tourism and children's right to the city.
