A study published in the journal Pediatrics indicates that 63 percent of pediatricians follow the American Association of Pediatricians guidelines and conduct developmental screenings of children at 9, 18 and 30 months. This is triple the rate – 21 percent – that a similar study found in 2002. Pediatricians who reported they do not conduct regular screenings were most likely to blame time constraints.
