Infants and young children, due to their special physiological functions, wearing a traditional mask is easy to trigger the risk of asphyxiation and other risks. Therefore, if in the personnel is not dense place, the air is relatively circulating place, you can just wear a medical mask, similar to the hat hanging on the face, can effectively shield droplets and other pollution. If you go to a crowded place, you can intermittently wear a mask, while paying close attention to the infant’s reaction, if the infant appears to be crying violently, depressed, purple, white, etc., the mask must be taken down immediately. At the same time, infants wearing masks is best not to wear continuously, every one or two hours to take off, so that infants can breathe.
