Hi.. Does anyone know of an app or setting that will allow my toddler to use his flash card app without toggling between apps each time he tries to swipe to the next card? The app that we use is pretty straightforward. A picture displays on the screen and a voice says what the object is. You can swipe to get to the next image but it seems like everytime my son goes to swipe to the next image, he does something that makes it toggle to the next open app. There's gotta be a way to disable app toggling, right?
