New at this too... but...
I really feel for you. Trixie is now 11 weeks, but she was seven weeks when I got her. The first night, cried for about an hour next to my bed in her crate. I had to get up five times during the night to pee her. The second night, she cried 20 minutes next to my bed, fell asleep, and then woke up about 3 twice during the night to pee.
When I took her out, though, I didn't talk to her (as the book I was reading suggested). I took her from the crate, swept her downstairs and outside, ignored playful behavior (it was easy to ignore this at 3AM!), and then praised her when she peed. Then right back inside and in the crate.
She would cry, but when I offered her a finger to sniff she was fine.
By the third night she was sleeping the whole night through, but had to PEE first thing in the morning. Now it's a routine and she knows the scoop. That is, crying in the night gets a finger or a pee, no play, no food, no fun.
If you really HAVE to have her in another room, then you'll have to deal with the crying until she learns it's not going to get her anything. Every word you say to Karma reinforces that crying gets her something. You have to be the one to decide what crying results in and then she'll decide if it's worth the effort.
Another thing I've observed through this forum and reading is that boxers need their pack in a major way! Perhaps teaching her to sleep in a high box next to the bed would be possible, and then upgrade to a dog bed later?
I wish you luck in finding sleep again... I didn't anticipate what a rough ride having a puppy would be, but I've found (so far) that it's worth the aggrivation!
