I have no experience, but maybe at the moment it seems a bit like an adventure and she is excited at the prospect of two houses? I would imagine it will become more real once the move has actually taken place
This is what I was going to post too!

My kids (well DD's) thought it was great fun having two homes... Until the novelty wore off. 2 years on, all 3 struggle with the concept of going between homes. We have a few problems we are still working out. They at least now understand Xdh and I will never be back together and both are remarrying new partners.
