I've been seriously considering getting my two DC a Yoto each. They don't know they exist but I'm confident that they'll love them. That being said, can anyone recommend the larder or smaller one? I'm not sure what the difference is (or if it's just size) and is there any difference with the headphones? Are the headphones the same socket as iPads/tablets etc? Also, do you think one is okay to share or one each? Thanks
