I have always brought my DD's home whenever they have needed to, which has meant 7 years so far of driving forwards and backwards to WL,Hammond and Tring from the Midlands, most weeks, with the help of the kindest friends along the way.
Personally, I think it is important to listen to your own child, not other parents or house parents. It is your child who 'may' suffer from poor mental health if not given the opportunity to offload. There is very little opportunity at vocational schools to do this in private and dancers very quickly learn that they are meant to develop a thick skin, and they may, whilst they crumble inside, learning to repress their feelings.... of course they may thrive. I don't know many young dancers who came through completely unscathed 😒
Every child/young person is different and only you can decide what works for your family 😊
