The use of "littler" as an adjective is relatively modern and despite now appearing in several dictionaries, I would still maintain, is grammatically incorrect. If I have two brothers and I am the eldest, then one is my younger brother, the other is my youngest brother. Even if you allow for "littler" being correct, the word would none the less refer to the physical size of your respective brother, not their age. Using language in the correct way has nothing to do with elitism, it facilitates understanding. What is the point of communicating with someone, in the same language, if they are not going to understand you. Gitit?
