Pediatricians across the U.S. are seeing a steep drop in the number of children coming in for appointments right now — only about 20% to 30% of the volume they would normally see this time of year, according to the American Academy of Pediatrics. Though telemedicine can make up part of the difference, doctors say the size of the drop-off in some routine well checks is a big problem — for those children and for the nation — though parents are understandably concerned about exposing their kids to the coronavirus.
