G is my hardest child to get a read on. You have to be patient. If you go at him too strong, ask too many questions or try too hard, and he’ll shut down and literally run away. He’s private and doesn’t want to share too much of himself, even to his family.
It’s also hard to figure out what he likes, because one of his strongest personality traits is that he wants exactly what everyone else has. Ask him his favorite color and he’ll give you the favorite color of the nearest kid to him. What does he want for Christmas? Whatever everyone else is getting. He has such a strong sense of equality and fairness. It doesn’t matter if a sibling has an m&m and he has a whole bag of marshmallows - if he doesn’t also have an m&m, he’ll be upset.
