Welcome to boxer world!!!
I agree with everything from the above poster, but just want to add:
She will like to have the crate as her own space, or her own little cave. I leave Cisco's crate door open at all times and it is not uncommon for me to find him napping in it!
I would make potty breaks at night just that, not a play time at all! If you do make them fun and a play time you are going to not be getting much sleep. And it is going to take her alot longer to get used to the crate. We have read many sad stories on here of puppies that were not crated and destroyed the house, or got into something that hurt or even killed them!
If you want to read up on any of these topics, use the search button at the top of your screen.
Hope the next few weeks pass quickly for you, I had to wait two days to bring Cisco home and THAT seemed like forever!
