MEH, it's end of term, and nothing much is going on, and the schools drop in days off whenever it suits for 'inset days' and have long holidays, (compared to most other professions.) And some schools are even thinking of dropping a day, and making the 'school week' a 4 day week.
So YANBU.
The school won't like it though. The students are only allowed to have time off/miss out on their education on THEIR terms...
As an aside, how lovely for your children, to be growing up on a farm!
I know quite a few people (maybe 12-13 people, from five different families,) who grew up on a farm, and every single one of them LOVED it, and have some wonderful childhood memories... Also agree that there is more to life, and 'learning,' than being stuck in a classroom (especially on a hot day!)
Personally I would keep them off til September!
I have always thought the summer holiday should start on 1st July, not 3 weeks later. I genuinely think that the summer holiday should be 9-10 weeks, not 6, though I do get that it may cause problems for families where both parents work (re; childcare...)
Finally, you can tell who the people are on here who don't live rural!
As a few posters have said, only us country folk understand where the OP is coming from!!
