Your 14-month-old's language and cognitive development: Say it again ... and again

From BabyCenter.com:

At 14 months, your toddler understands many more words than she can say. Her spoken vocabulary likely consists of about three to five words, typically "Mama," "Dada," and one other simple word such as "ball" or "dog," but she learns the meanings of new words every day. As she starts to add words to her vocabulary, you'll notice that she looks for opportunities to practice them. Once she can say "dog," for instance, she'll look for dogs everywhere — in books, outside, on videos — just so she can point and say the word over and over again.
