So according to recent research, babies can recognize their mothers and fathers about 24 hours after being born (mostly by smell, since their eyesight is pretty limited for the first few weeks, and possibly by the sounds of our voices, since they hear us so much inside the womb). In Developing Young Minds, Shore looks at neuroscience research that suggests that whatever isn't used in the brain, the brain will prune away and discard, so if your baby isn't introduced to a variety of healthy stimulation in his or her first three years, they've already lost thousands of brain structures that would support learning.
Developing Young Minds looks at what the infant mind is like, how babies learn, and how parents and other adults influence a child's development. This opened my eyes to a lot of information I was pretty hazy on before but that make sense to me - babies are programmed to learn quickly and fairly efficiently (after all, most children can speak pretty well by the time they are three or so, whereas many adults take years to learn a new language and they can already speak one!), and they respond to increasing complexity in visual images, speech, and music.
Shore backs up all her assertions with detailed source research, and it's pretty fascinating. I wasn't sure I was going to like the sections on music for babies (playing classical music for your baby seemed like something neurotic wealthy parents who want their kids to go to Ivy League colleges would do), but she actually has me convinced - Bach (and Baroque music in general) is the way to go for first baby music, and then you can move on to the Classical and Romantic composers. Along the way, I learned a who lot about JS Bach and Wolfgang Mozart as well, so that was a bonus.
Shore's own research is particularly interesting because it suggests that children need dedicated intellectual stimulation and learning opportunities well before they start school at 5 or 6. By that time, some children are so far ahead of others in terms of learning abilities that it's really not fair to put them in the same class. Shore makes such a compelling case for early childhood education beginning as soon as a mother leaves the hospital with her baby, that I started to get all activist-y and thought about writing to some politicians (amazing how fast that impulse dissipates when you start thinking about most of the politicians in this country).
