The COVID-19 pandemic has greatly altered family life, and research among adults and families is finding increases in financial stress, mental health problems, screen time, parental conflict, and child behavior problems. Given these patterns, we sought to replicate these findings with a younger and largely non-white sample and consider how these constructs might relate to each other by using the Family Stress Model. From surveys of 247 predominately Latine mothers and fathers of children under 4 years in the U.S., we found that financial strain was related to childrens media exposure and use, largely through impacts on parents mental health and coparenting relationship. Interestingly, only use of television in the background and during mealtimes were associated with increases in childrens behavior problems. Such findings better capture how stress may operate in a family system and offer a way to counsel parents about healthier media habits for children.
