If you can get a blankie or soft toy that had spent some time with the puppy and its littermates/mum, you could leave that in the crate to comfort the pup (familiar smells!).
Tiring it out helps the pup go to la-la land faster too.
That said, it is important that you do not give the puppy any attention (eg. talking to it, looking at it, touching it) if it is whining in the crate (assuming it does not need to pee) because it will learn very quickly that it can whine to get your attention! And the whining will just continue and continue. What you can do however, is to praise and give the pup a little pat, WHEN IT IS QUIET (ie. reward the pup for not whining). Make sure you wait for at least 3 secs of quiet if its been whining before you praise the pup tho'.
Good luck! Love puppies!! As BCPuppy said, they are adults before you know it and you'll miss those puppy days! Take lots of pictures!!
