Language learning begins with
listening. Individual children vary greatly in the amount of listening they do
before they start speaking, and late starters are often long listeners. Most
children will "obey" spoken instructions some time before they Can speak, though
the word "obey" is hardly accurate as a description of the eager and delighted
cooperation usually shown by the child. Before they can speak, many children
will also ask questions by gestures and by making questioning noises. Any attempt to trace the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves out as particularly indicative of delight, distress, sociability, and so on.
