My eldest is just finishing a full boarding coed school. She went at 13 when they started and she has loved it, mostly.
She's maybe seemingly a bit different from a child whose been to a day school but she is not hardened or someone who has had to "survive". It's all positive. She is a vibrant, fun, engaging girl who has benefitted from a family feel of a boarding house, has made best friends for life, and has never ever had to deal with school commutes! Her day is much more balanced with work and play and sport than a day school as the time scale is extended.
She has gently grown into a lovely mature adult. She's not going to be one of those freshers who go crazy this September when she goes to university. Maybe people will think that's a downside? Probably the same who say that "sending your child away" is unnatural. Why such an arbitrary age? I'd argue my 18 year old needs me now more than 13 🤷🏻♀️
It takes a village. A boarding school who are good at pastoral care share that responsibility with the parents are part of that village. It's a partnership and for me it's always felt like a rewarding one.
Boarding school is very different to 20,30, 40 years ago. It's incomparable. It's like trying to compare BBC in the 1970s with Netflix 😆
For us, it's just an extension of us, our family. And DD has flourished. It's doesn't suit everyone, it doesn't suit every child, it certainly doesn't suit every parent. But I am certainly not in either the helicopter or benign neglect camp. I am just a normal parent.
