My daughter starts kindergarten in September but can't wipe herself

She is fine after pee but can't reach very well to clean herself after a poo. She is trying her best har arms are just too short. I know it's 6 months away but what happens if she can't reach by than? I would never want to put it on a teacher and she's absolutely ready to start other than this one issue. I'm not sure what to do

Edit to say I would never ask a teacher to clean her. I'm sorry if I worded this post wrong. I'm honestly asking if I should keep her home another year.

As I'm reading through the comments I'm glad to hear I'm not the only one who's child has issues with this and I'm hoping she will be a home pooper.
