I think I remember asking about that on the forum. I think I was told that it wasn't his son that played baby Henry.

Genuinely, I thought baby Henry looked like Colin's wife at one point, so I'm really surprised that there may be the chance that he wasn't even played by Evan. Whether this is true or not, baby Henry was so so cute. When he was in his holder in Regina's Vault, his little face and big blue eyes...I melted! <3
