I myself went to a major public school (Cheltenham Ladies) and haven’t chosen to do the same for my own children for various reasons.
my SIL, who can be a bit highly strung, has two sons who currently attend a nice state primary. She has announced that she’ll be sending them to the (big name) boys public school about 15 minutes away. I have. A lot of experience with this school and I do not think her boys are the right fit. They are lovely boys who I adore but I don’t think they’d cope there. My SIL has hit the roof. IL’s tend to pander to her a bit and Have suggested to her that I was unreasonable in my advice.
DH and IL’s attended a good Grammar school and I just don’t think she appreciates how robust they’ll need to be to jump straight from a cosy village state primary to a major public school. Happy to be corrected if people feel I’m being unreasonable?
