Didn't they just come out that regular mask don't work hence Biden buying medical grade mask to be put in stores for non medical people? Those mask you can tell do a good job of keeping mask tight and on your face you can see the marks on Dr. faces when I visit them. I am not sure little kids would be able to wear something this restrictive on their face I got to give Dr. and Nursed a lot of respect because I couldn't not be wearing that for 8 to 12 hours a day
