I didn't watch this because I went to boarding school at the same age for the same forces reasons. It would have brought back the sadness.
I felt heart wrenching homesickness. I used to fall asleep on a pillow wet from tears, sometimes relieved the crying had started knowing that I would cry myself to sleep in the end. Homesickness is like a horrible grief. I suffered bouts of it throughout my school life.
Having said all that, I liked school. I liked my friends, it was fun and rather like Mallory Towers! It was so much better than changing school every five minutes which is also very upsetting because you can't ever develop any friendships. Boarding school can represent security. I felt quite grown up at eight, of course from an adult's point of view an eight year old is tiny but in the position of such a child you learn to cope with your friends around you. Homesickness comes in fits and starts if you're generally happy at school. It's one of those things you learn to live with, like grief. We used to talk about feeling homesick with each other in the dormitory and there was always someone to comfort you.
Although the feelings of homesickness are terrible, being a forces child it isn't so easy to feel resentful because the other option wasn't great either.
All my forces friends went away to school so it was normal and I wanted to go. Most people coped with the sadness and as an adult I certainly only get really upset about things that are really worth expending the energy on. If nothing else, it taught me perspective, self sufficiency and coping skills.
Of course you don't need boarding school to teach you these things but for me it was a good by product!
I sometimes think we underestimate children, and it makes great TV to watch little girls crying for their mothers but although I didn't see this programme, unless they were horribly unhappy with school in general, I can't believe there weren't any really great, fun, happy moments shared with caring staff.
My children won't go to boarding school. If my husband were in the Forces I would homeschool but I bet my DCs would want to go! It's very complex.
