Encourage your child to use language to express ideas, observations and feelings. Read and tell stories that have interesting characters and discuss the stories together. Help build your child's vocabulary by introducing new words, speak in full sentences, and give the opportunities to answer questions and talk to other people instead of answering for them.
Using words to describe to your child your actions throughout the day can help them understand language. For example, when getting a snack, you could say: "First, I am going to wash the apple, then, I'm going to get a sharp knife to cut the apple. And once I cut the apple into smaller pieces, we can each have some." When introducing a new word, it is helpful if you repeat the word in different situations so the child sees the different ways in which it can be used.
