Yes I agree He always knew, but was His humanity always
conscious of it before age 12? That, I think we’ll never know. If His humanity was always conscious of it and He had the human mind of a 2yr old when He was a toddler, how did He never in His human child mind never set something on fire when He had a temper tantrum? Or get mad at 1yr old and stop the sun from rising? LOL!

He was 100% human with a human child’s mind as a toddler. I think a part of Him always knew, but that maybe He wasn’t consciously aware till He was mature enough to start to understand it like around 11 or 12yrs old. His divinity side might have deliberately blocked it out from His conscious mind the way people block out bad memories, till He was humanly mature enough to know and understand.
