Help with puppy and potty training at night...?

As soon as I brought my new puppy home (I did as recommended and took my older pooch to pick her out) she was instantly much farther along than anticipated. She has a distinctive bark and head movement she does when she needs to go outside to potty- thus far no accidents indoors :) She has a crate to sleep in that I've placed close to my bed. The first two nights she's made the sound, and I've woken up to take her out, then bring her back in and let her fall asleep nuzzling my hand. After 48 hours with a grand total of about 14 hours of sleep, I'm looking for another option. I can't keep waking up this often to take her outside. My friend suggested making a "tunnel" to a little box with a wee wee pad in it that she can use at night; something away from her bed, but confined so I don't have to keep waking up. As great as this sounds in theory, I'm afraid to try it because I don't want her to think she doesn't have to signal during the day... I'm planning on asking my vet in the morning, but until then, any ideas/suggestions/insight on what I should do tonight? Am I just being paranoid that she'll "forget" her potty movements all together? I know that puppies are not able to process complicated concepts like night and day without the help of their owner. Should I try the attached wee wee pad, or just suck it up and keep waking up every few hours... Thanks!
