Children must choose themselves weather to wear masks, There is no plausible justification for introducing mask mandates at this time. And since mask mandates belong to that class of infringements upon liberty that can only be legitimate if there is an emergency, also COVID infections tend to be harmless for younger children, the pandemic also comes at a crucial time for developing skills important for empathy, safety and more - a phase that some parents worry will be impaired by mask-wearing. There are sensitive periods in early childhood development in which language development and emotional development are really rapidly developing for the first few years of life, so I believe that all mandates for wearing them should be ended immediately.
