I'm saying 146 and a 4.5 yr old.

I wish I could see him from the side, though (age-wise).

Take it with a grain of salt. I'm a complete novice at this. I'm looking at his face structure, transition in his neck to his body, and overall body mass. Also look at how wide his neck is compared to his face (and again,.....that face is no small one).

He could easily be older.
