Let's watch a parent-child interaction with a mother who is responding positively to her child. Notice how this mother repeats what her child says and uses words to name ingredients and extend what her child says. She uses words to explain what her child is doing when she has measuring cups. She also explains the usefulness of the measuring cups. You can think of this as answering a question a child could have asked, but didn’t. She promptly replies, showing that she is paying attention to her child’s comments, but also waits after responding to let her child process what has been said.
