Several years ago, my one GD was not quite 2. She HATED the human characters. Peter Pan, Cinderella, Snow White, Mr. Smee, etc. She would have nothing to do with them at all! But, she adored the characters like Pluto, Chip & Dale, Mickey Mouse, Donald Duck. She would reach out or run to them & love on them. I think, in her eyes, they were just overgrown stuffed animals.
I assume your young one has some of these Disney stuffed animals. Does she cuddle with them? Do you call them by name. ‘Here, Sweetie, is your Mickey Mouse. Give Mickey a hug.’ (etc) If you do the same in the park, she may associate the larger animal characters with her stuffed ones.
If she doesn’t like the human characters, don’t force them on her. What we did was have our picture taken with the character on one side of us while holding DG on the other side of us. She felt safe and we still got a nice picture.
