Unstandardized beta coefficients (b) and corrected p‐values (p) from the linear mixed model are shown for the following factors: caregiver's stress, quarantine status, time caregiver spent on mindfulness practices, presence of siblings, time caregiver spent on childcare, presence of pets, change in caregiver's working arrangements, child's age and sex. Missing values indicate that the factor did not survive statistical backward selection. Significant associations (p < 0.05 after correcting for multiple testing by means of the false discovery rate) are presented in bold. Results are based on the baseline assessment and considering the change in sleep variables from before (assessed retrospectively) to during the confinement (April 2020). We note the difference between sleep variables for the two groups of children, with babies’ sleep assessed in absolute terms and preschool children's sleep assessed in terms of frequency according to a 5‐point scale.
