I would not be entirely surprised if he’s taking his cues from A woman cannot survive on wine alone she also needs baby Yoda shirt and letting people underestimate him. Well, we haven’t seen him talk at all yet. But he is 50 years old, and there are definitely moments where it looks like he might understand what he’s being told shortly before very deliberately doing the exact opposite. Someone noted looking at him that he is a carnivore. If you remember, Yoda had sharp little piranha teeth. Sharp teeth are indicative of a carnivore. We see The Child constantly trying to eat frogs, so clearly that is a preference.
Granted most people know this and are only using the name A woman cannot survive on wine alone she also needs baby Yoda shirt for The Mandalorian character as a placeholder until we learn either his real name or at least name of their species. But there are indeed a few people genuinely confused and think this is really Yoda as a baby, and not a Baby Whatever Species Yoda Is Baby Yodarian. But yes, the Baby Whatever Species Yoda Is, aka Baby Yoda character on the show The Mandalorian is indeed a canon character.
