How much does your baby know?

Young babies don't do a lot, but every year we discover there is a lot more going on inside than you can tell. The latest news is that four-month-olds already have an idea about the shape of a word. EEG measurement showed that infants this young recognize patterns of word stress that are specific to language, and they are better at recognizing words from their own language. Previously, only 6 to 12-month-olds had been shown to have knowledge about their language. Current Biology.
