Question: why yoda is a baby in the mandalorian?
Answer: Yoda and Yaddle are the parents. They hid baby Yoda because its force powers were so terrifying and, of course, Yoda and Yaddle broke the Jedi code with their lovemaking. Little Yoda could easily be far worse than Anakin, and was sent away to a desert world. Baby Yoda is the reincarnated body of old Yoda.
