I think any time you have children involved, it very much complicates things and makes them more difficult.
It would be just as difficult as it is for any normal person who goes to a young child or a teenage child and says, “By the way, we're going to leave this community and go to a completely different community where you have to start all over”.
Certainly, there are lots of challenges, but I am not familiar with actual research or studies that have looked at the issue, though.
