A High-Pitched Buzz and Training Wheels - S2-E1
Continuity mistake: When George gets out of bed to go and comfort Mary at the window, he puts his hand on her shoulder. When the camera changes to a view from the front, the hand on her shoulder has gone. (00:09:50)
Answer: It is shown numerous time in The Big Bang Theory and Young Sheldon that Georgir Jr is not the smartest kid going. They simply tell him Sheldon is getting a hair cut as it is believable. It's also shown that Sheldon has had the same style hair cut since he was 5. Since he is 9 in Young Sheldon, he's had the same style for over 4 years already. Easy to overlook that he hadn't actually had it cut after that long.
