We communicate clearly with children so they understand what we are saying to them & asking of them. Clear communication is important otherwise children could feel confused by long, detailed sentences. Etc
Issues with bilingual children are that they may not know as much English so you'd have to adapt your practie to suit them so they can understand you. This may mean using very simple language, picture cues, sign-along etc. You could also learn some key words in their language.......
Hope this gives you a start.
