I studied psychology for a couple of years as a personal hobby, so you start learning about people and listening to your intuition, like when you you're feeling that people are not being entirely straight with you.

The science can tell you that the thousands of pseudo-scientific parenting books out there - not to mention the 'Baby Einstein' DVDs and the flash cards and the brain-boosting toys - won't do a thing to make your baby smarter. That's largely because babies are already as smart as they can be; smarter than we are in some ways.
