Hi, look at what you've written about children's communication and how it changes over time - as they grow, become older and develop. Then use your work place experience for examples eg. times you've seen/observed children using language (body and verbal) to communicate. Think about how old they are, what the communication is and how that links to what you know is expected development.
your handbook may help?
