Analysing the CDS techniques used in 'Zach 2;4'

CDS Techniques-

Halla asks Zachy lots of open questions throughout the video, for example early on in the video Halla says "what Darling?" Halla does this to let Zachy talk and give him the power in the the conversation, the combination of interrogative and endearment helps to show that she is giving Zachy the power in the conversation. The use of tag questions comes up in the video too, for example Zachy says "(.) a banana (0.5) and 3 things in the banana (0.5)" Halla replies "a banana and what? (.) 3 things?". Another technique Halla uses is repetition, it seems that Halla often appears to repeat what Zachy says when he mispronounces a word like "frough" Halla will repeat the sentence using the correct pronunciation, this is seen when Zachy says "it doesn't go frough" Halla answers with "it doesn't go through? (.) why not" Halla does this to influence Zachy to copy her and attempt to pronounce the word correctly. Halla does this again with "bolognay" and "bolognaise". Halla makes sure to praise Zachy so he knows she is happy with him, this also influences Zachy to do it again and build up a routine. We see this when Halla says "you are a star (.) little man".
