It’s not how you say it, it’s what you say "Concentrate" 

Children need to hear language being used to talk about things they can see and feel, what they have just experienced or are about to experience, what they are curious about and what they care about. This is the type of speech that provides children with the raw material they need to learn a language-to figure out what words mean, where a subject or a direct object fits into a
sentence, how to ask a question, and all the other things that make up language.
