Assalamualaikum ustadh. I think I commited kufr accidentally. My sister she's 3 I've been teaching her that Allah is above the seven heavens she says sky. I'm still teaching her. I said yeah when she said it again while I was teaching her. I meant yeah, then correct her so does this mean agreeing?

Don't fall into waswas. There is nothing in this, inshallah ta'ala.
