Quoted from Psw757:If it was a clone it wouldn’t be a child would it?
Yoda was approximately 800 years old when he died if I’m not mistaken and this child is 50 isn’t it?
I think that was said in episode one so I’m thinking it’s offspring of Yoda. We will find out soon I’m sure.
From what I learned, the clones (from Episode 2) age at twice the normal pace as a regular person. If that's the case for baby Yoda clone, he would have been cloned 25 years prior to Mandalorian, which would have been several years after the end of Episode 3. All theory and speculation.
