I actually have little pim in several languages and my little one asks for all of them at different times. I am planning on purchasing the german and russian version of little pim, but for now I have material that I am teaching him in those languages so I will focus on those first then move on to little pim when we have learned all the material.
I had similar worries when I started getting more and more little pim in different languages, but when my son enjoys something he will watch it, so it never stayed an issue. When we are watching a particular one, for know which one I was going to play. Because I use sign to connect the different languages I also would sit and watch the videos with him and sign as much as I could throughout the video. Now that he has been watching them for a little while he will watch it with my older children and they will repeat and/or sign what they hear and it never fails that he always has to ask for either an apple, banana, water, or milk whenever he watches it
He has been exposed to all of the languages that I purchased, so he knows what he wants to watch and in what language when I ask him. Hope this helps and take care!!!
