The constantly talking is a form of parenting taken to the extreme of course - yes we are told in all the good baby books to respond to our child's cries - but we all know response time can allow us to go pee or swallow that last bite of lunch before we do. The baby books say to talk to the child and help them explore their world as a way of encouraging language - what it does it cause the child to shut down and not hear a thing the parent is actually saying - like a drone of noise in the background of their day. If parents only realized instead of teaching language they are teaching their child to ignore them.
