The hospital where we had Noah sends a weekly email on development and other items of interest. Here’s part of the “Week 50″ newsletter:

The importance of talking

Talk, talk, talk, and more talk. The effect of talking to your baby-chatting, describing, explaining, singing, asking, echoing, rhyming-is enormous and lifelong. A classic study of 42 varied families showed that the most important aspect of children’s language experience is its quantity. The amount of day-to-day talking that parents did with their babies and toddlers was closely tied with the children’s vocabularies and IQ test scores at age 3 and beyond. The researchers sum up the results of their data: “As the children learned to talk, the amount they talked increased steadily until it reached the amount of their parents’ talk, and then it leveled off. By age 3, the children were talking as much as-but only as much as-their parents talked. Furthermore, the children’s talk was as varied-but only as varied-as their parents’ talk.”

Heh.

So that’s why Noah seems like such a chatterbox!
