It can be nearly impossible for parents to know their child has a learning problem before he or she starts school, but nearly one-third of this country's children do have trouble reading, which can lead to serious problems down the road.
There's a little-known, free program that has screened about 13,000 preschoolers in the area at day care centers, libraries and churches since 2005.
Nemours BrightStart visits places like Little Britches Day Care and screens preschool children for literacy delays. Experts say finding a reading problem early can have a profound affect on the rest of a child's life.
"We know from research that if children start first grade behind their peers, there's a really good chance that they're not going to catch up," said Maureen Saunders, of Nemours BrightStart.
