Well-meaning relatives and pediatricians sometimes offer assurances that an infant or toddler or pre-schooler with a delay is a “late-bloomer” that will catch up and advise parents to “just wait.” Yes, all children develop at varying rates, but a parent often knows when their child is truly not developing in a typical way. Trust your instincts as a parent: Waiting is not a good idea! Most children struggle during some part of their school years. This is common and some help over hard spots will remedy this problem. But if you detect your child has continues problems with reading, writing and math, he or she may have a learning disability. Often children with learning disabilities have symptoms. These symptoms do not disappear, as child grows older. Detecting them is key to a successful approach to helping your child.

Remember when Cher had a huge hit with a song called 'Believe'? That strange warbling effect on vocal is actually created by pitch correction software. Someone discovered that by setting it to over-correct it would actually produce a pleasing effect. Like all these things it has been over-used since by many artists.
