From the Document: "Like any tough subject, Coronavirus (COVID-19) can be challenging for parents to talk about with their children. It is natural to want to 'protect' children from unpleasant information. However, young children, even infants and toddlers, pick up on emotional changes in the family, and at times assume the worst. Most children have questions they need answered. When talking with children about coronavirus, parents should find a relaxed time and place, and provide sensitive and responsive caregiving while addressing their children's questions and concerns. When parents feel calm and clear in their own understanding, it is easier to be calm and clear when explaining tough topics to children."
