This book starts by describing a baby’s language development alongside their physical development in the first 18 months. It then discusses play—the way young children learn. It also explores childrens' very early acquisition of words, and how they use them, and it covers the exciting development when a child can put two words together and talk about more complicated things. Lastly it looks at the variety in children’s progress with language which can involve particular stages, such as saying "no" and asking lots of questions. The end of every chapter offers a summary of tips for parents.
