That depends on presentation. Have him play with some of the halfling children, give then rides. He would be way less scary with a giggling 5 year old riding him like a pony.
I do not think it does, you could have him juggle laughing babies with his snout and it is still not going to get Sofia to forget the terrors that made countless big bad wolf stories across the world. It is not just that this is a scary predator, this is the most successful and resourceful scary predator in the old world. No one who was raised in a village will ever see a wolf and not think of their potential to rip out throats.
