[Families with infants and toddlers in the COVID-19 pandemic: parental stress and child development considering social class]. / Familien mit Säuglingen und Kleinkindern in der COVID-19-Pandemie: Belastungserleben und Entwicklungsauffälligkeiten unter Berücksichtigung der sozialen Lage.

INTRODUCTION: It is now well established empirically that families and children who could not attend educational and childcare institutions during the COVID-19 pandemic experienced disadvantages. This is particularly true for families in poverty. However, little is known about the situation of families with young children. The aim of the paper is to investigate (1) to what extent families with infants and toddlers also experienced their situation during the pandemic as stressful, (2) whether there were differences depending on social class, (3) how the pandemic affected the healthy development of infants and toddlers, and (4) to what extent class-related differences can also be identified in this. METHODS: The German National Centre for Early Prevention conducted a nationally representative survey of families with children of age 0 to 3 years in April to December 2022, "Kinder in Deutschland 0­3 2022" (N = 7821). The KiD 0­3 study combines a parent survey on family psychosocial burden and resources with pediatric documentation of child development. RESULTS: Parents with very young children experienced their situation in the COVID-19 pandemic as stressful. A clear difference depending on social class emerged. Both from the parents' perspective and in pediatric judgment, the pandemic had a negative impact on social and affective development even in young children. These effects were more pronounced in children from families experiencing poverty than in children from families not receiving basic government benefits. DISCUSSION: In order to mitigate the psychosocial consequences of the COVID-19 pandemic for families and to improve children's chances of growing up in a healthy way that promotes their development, it is necessary to support families in need without stigmatization.
