There are two key ways you can help your child develop language. One is to read to them a lot. The other is to talk to them.
A day in the life of you
At bedtime, tell them the story of what happened in their day. The skills of sequencing, prediction, retelling and remembering events are all developed through this activity.
What, who and how?
Take turns asking each other a question. Try to ask open-ended questions that require more than a yes or no answer.
Odd one out
This can be played in several ways. If focusing on rhyme, you could give your child three or four words in which one doesn’t rhyme, like cat, mat and dog and ask them which one ends in a different way or sounds different. You can also do this with synonyms such as happy, glad and angry - which one doesn’t belong? This is a good way to extend vocabulary and explain new or rarely-used words.
