What is better to do?

What is better to do? so I have a classmate with a very noticeable stutter and it takes her a while to get a sentence out. I don't rush her and I listen and wait very patiently but I was wondering if looking her in the eye would be...idk like it's rushing her? should I look her in the eye until she finishes her sentence or look elsewhere ever few seconds? I feel like either one is rude so I was wondering 😭
