I agree with the others..I would not bring it up again. It wasn't the mom who said it. However, I think since this child only comes very part-time and often half days, there is little hope she will improve at naptime unless parents are following the same routine at home (which they are not). For me it would not be worth the stress and headache to have a child one partial day per week. Also, I am wondering why the white noise machine are in and outside of the screecher's room? They should be next to the other children to block out the noise.
