I agree - Sienna would thrive at a regular school once she caught up/got settled. She went to 'alternative' schools in Brighton and in Dubai and seemed to really like the interaction with other kids.I feel so bad for the girls and their lack of formal schooling. Like others have said, it will undoubtedly affect them in the future. It's probably too late for Mia, but I wish they could send Sienna to boarding school. It's not ideal as she's so young but it would give her a stable home, new friends from different walks of life and better her education. Even if it was a more 'free-spirited' school like Summerhill, it has to be better than her situation at the moment. She would probably thrive in a stricter school but I doubt her parents would ever consent to that. They have the money to do so.
Can't see them ever allowing any of their kids to go to a boarding school though. It was mentioned in the previous thread that they wouldn't let the girls go and stay with Georgie's sister and from videos we know that Sienna has only ever stayed one night at their grandparents place in her whole life. We've never seen the girls going to any sleepovers or even to a friends house to play - their friends always come to them. It seems like more of a control thing.
