By the time Kaladin flies back to Alethkar after the battle at Thaylen City, Gavinor appears to be three or four years old, with chapped lips, haunted eyes, and is dressed in rags.[1]

So he’s probably 5 now or around that age
Calm down.
So what proof do you have that Dalinar finds a 5 year old to young to fight.
If Odium calls Kal as his champion Dalinar win because Kal would suicide himself.
He can’t be a champion because he won’t be willing, that was the point.
For now...
What’s this mean?
