night waking in crate training

Question
QUESTION: Thank you so much for answering my question!
I have a 14 week old pup. We've had her since 9 weeks, and were fortunate to get her from a great breeder. At the breeder's house, she had access to the backyard, and came home with most of the idea that she should go outside for toileting.  Of course, she's still young. To be fair, she has had very few accidents, and those she has had were my fault because I wasn't paying attention to her cues or watching closely enough. She's never defecated indoors - we're very lucky!
During the day, she is either supervised in our kitchen/dining area, or if i can't supervise her she's in an ex-pen with her crate inside with the door open. she usually chooses to sleep in her crate. We are able to leave her 3-4h max and she will be clean in her pen when we get home.
Our problem is nighttime, however.  Since she came home, we've been crating her next to our bed.  Our previous dog slept on the bed, and although we miss here there every day, we decided the new dog should sleep on the floor (my 10 years worth of backache is starting to improve!).
Puppy settles very well at night in her crate, but still wakes at least once, scratching to be let out (usually 3am).
I follow the advice, take her outside wordlessly, no priase, let her relieve herself, and back to bed. She then settles well.
Last night we went to be at 11, she was up at 3:14 and again at 5:10.  
My question is this: should  I
a) move the crate out of the bedroom and ignore scratching
b) keep crate in the bedroom but ignore scratching to break the habbit (but have several sleepless nigths, I'm sure!)
c) contiue to take her out because she should outgrow this
d) another alternative?

i really appreciate any advice you have with this.

ANSWER: At 14 weeks all of our puppies were able to go overnight.  Make sure she walks around enough outside to stimulate urination on her last trip outside at bed time.  One quick dribble may not leave her bladder empty.  You may also want the vet to check her.  Make sure her crate doesn't leave too much room to move aroud.  If she has much more than enough room to stretch out, she may be too active to make it over night.  If none of those help, try leaving her and see if how it goes.

QUESTION: Thanks for your reply
The crate is small enough - only big enough so she can stand up, turn around and lie on her side comfortably.  I will try to make sure she does more than "1 squat" before bedtime - this is a good idea.
I personally think the problem is more behavioural, and she's gotten used to my responding to her when she wakes up.  Just wondering if moving her out of the bedroom would be hard on her, as she's used to being close to us.
She sees the vet very regularly - no problems health wise, and  her urine is normal.
and of course I will be spaying her when the time is appropriate.
thanks again

Answer
Yes, moving her out of the bed room will be hard, but may help.  I have never had much luck with the old clock or radio tricks. What I do is lay down by the crate like I was going to sleep there. Usually a puppy may fuss a little, but then settle down and go to sleep. Once it is asleep, you can get up and go to bed.
