As someone with Autism that had a child that started to speak late, I can sort of relate to him being worried for the crate at which his child is progressing. It is a very realistic fear, very understandable. I didn't want my son to have Autism because of the difficulties I had growing up.
Also, yelling at your child is common. He OBVIOUSLY doesn't abuse or neglect Byul. Is it right? No. Is Byul gunna be ruined forever because he was yelled at like 4 times in his childhood? No. Is my son going to be ruined because sometimes I get overwhelmed and yell at him? No.
Stop freaking out and realize that life is more complicated than you'd imagine. Until you are in a similar situation, you have not got much room to judge.
Ok I don't even have a penis and those canine teeth made me nervous lol Could you imagine how bad a slip up would be?
