I think you're bound to have your children's happiness in mind. It's only natural. About the forum posts you've seen, once again, don't forget that it's people who are fired up about something that has gone wrong who are likely to take the trouble to write about the school. We don't expect to read, 'The children did lessons in school all day, and played outside, and nobody fell down and hurt himself, then they came home and told me all about it,' even if it's true, because it's not 'a story', and yet it's possible that every member of the forum with children COULD have reported that at the end of every day this week.
By the way, I have two grandchildren very happily at school in Auckland. There has been the odd moment down the years, but it's been dealt with.
