I also can see both sides but IMO, it's not really an unnecessary expense on the parents part. They need care Sept to June and if they can't find a dc that runs/charges those months only, than it is necessary to pay their provider for July/August if they want care the rest of the year. I have had parents who have 6-8 weeks holidays with their job as well but it's spread out throughout the year...they don't get a discount either (aside from my holiday fee I charge if they want to keep child at home) so I don't really see the difference between them and teachers. I do think that dcp's who don't charge them for July/August is of course the better option but I don't think necessarily think it's an unnecessary expense in the grand scheme of things.
