Teaching English To An Au Pair

I am giving a student a 1 month intensive crash course in English before she goes to the States to work as an Au Pair.

I want her to see what American kids are like before she gets there so that she knows what to expect. Are there any movies she can rent which have scenes with au pairs and kids interacting? I think the dialogues used in those scenes could be useful for teaching.

I am also thinking of using movie clips of language commonly used by American kids too e.g from the movie kindergarten cop.

Thanks
