Puppy crying all night

I'm a firm believer in leaving pups with their litter until at least 10 weeks.....that said, you should put her in her crate, place that on a table or whatever next to the bed so that she can SEE you, and go to bed.  What I will do is put a finger through the door if a pup is fussing....if s/he settles, s/he just needed reassurance.  If not, it's time to get up and take them to potty.
 
Your pup is an infant, away from "home" for the first time, away from his/her siblings and likely terrified.  In the wild, being left alone is being left to die, so it's pretty scarey stuff being left in the kitchen.  Put her crate beside your bed.

Get a crate!!  Put it beside your bed and shut her in it at nighttime.  With her bladder so small and weak, you will need to get up in the night to let her out for a few nights as she will not be able to "hold it" all night long.  Puppies usually have an inbuilt compunction about making a mess on their bed, so this will encourage her to "hold it".  Being close by you and in the restful atmosphere in your room should help her to settle.  If you want her to sleep in the kitchen, move the crate down there gradually later on. 
 
Used properly.....
 - The crate will become her "safe place", somewhere to go when she feels tired, lonely or scared and she will feel better just because she is in there. 
 - The crate can make the house training process much quicker and easier. 
 - It gives you a place to put the puppy when you are unable to supervise so she can't chew up your furniture or pee on your carpets. 
 - If ever play gets too rowdy, it;s a great place to put her to calm her down. 
 
It's important you introduce the crate sensitively.  Make it a really wonderful place to be and never use it as a punishment. 
It's also vitally important she is not forced to soil it - this will be enormously distressing for and will set house training back by months. 

This poor puppy is lonely and missing her mommy & siblings.  She is also scared and will cry until she trusts that you will be her new mom and will soothe her fears.  On your bed obviously is not a good place. Neither is in another room by herself. But NEXT to your bed in a crate, or small box with a stuffed toy is.  The box should be high enough so that she cannot crawl out.  The box or crate should not be so large that she will have room to sleep and pee in another place.  Should be next to you so that if she crys u can easily reach down and soothe her.  You cannot expect an 8 wk old puppy to be house trained.  When she cries, take her outside and tell her, lets go potty, or whatever words you choose, so she'll eventually know what you expect.  Don't let her play but go OUT WITH HER and tell her, lets go potty, hurry up, etc.  She will still have to find the right spot, and when she is finished praise her in your  best baby talk voice and she will catch on easily.  You have to remember, she is a baby and babies don't come without fear and trained.  Good luck!

Good points from cubby.... size of the crate is relevant, if you have a large breed puppy you might need to partition it off so she can grow into it.  It is just as useful for adults as pups.  It just needs to be big enough for her to sit up, lie down, stretch out and turn around comfortably - no bigger.
 
Set an alarm to wake you at night to let her out to do her business.... far better you wake her than the other way round, you don't want to teach her crying will make you come running and let her out!
 
Give her her favourite treat when she goes outside and save that treat for pottying only.  Keep a pot of them by the door so you can grab one or two on your way out.  As she goes, say your word, then walk up and treat - she should know its for toileting not recall and the closer the two are together (potty/treat) the faster the penny will drop.  After a couple of days you'll be able to say the word to prompt her and this is really really useful in the middle of the night and it's cold and you just want to go back to bed! 

This has always worked for me in an extreme case.
Old fashioned ticking clock, warm water bottle covered in towel, and in a crate right next to your bed.
 
I don't know if you can sleep like this, but leaving a radio on low volume helps, too.
 
Good luck[]

As a first time puppy owner, this board was my salvation - LOL! My little pup cried all night the first night as well; in his crate downstairs in the kitchen. We tried bringing the crate into the bedroom, as suggested here, but it didn't work for us. What DID work, was my sleeping on the couch, with Rudy in the crate next to me. I put my hand down on the crate and let my fingers inside a bit, so that he could smell me and know that he wasn't alone.

We also bought a little stuffed dog that you put in the microwave for him to cuddle with. He LOVED that thing! We called it his "baby".

Good luck! It will get better!!

Honey HATED her crate for the first couple nights and screamed all night.  It was heartbreaking the first night.  She was in the livingroom and I was up all night with her.  Here is what worked for us. Our kitchen is off the livingroom and her crate covers the doorway.  She is allowed to go either in the kitchen (easy clean up if necessary) or in her crate because we leave the door open.  As soon as we let her have "an out" she stopped freaking out.  We have never cleaned up a mess in the kitchen and we get some needed sleep.  I totally agree with the sleeping next your bed if you have the room...we do not unfortunetly.  I slept on the couch the second night and my husband the 3rd night. The 4th day of NO sleep we came up with the idea of her crate being left open to the kitchen.  Thank goodness it worked. In the beginning the only way she would go near her crate was if one of the kids was in it!  Here is a pic of the 1st day we had her.  Good luck and it does get better....we now have our 1st month under our belt and feel a lot better of our newest family member thanks to some great advice on this board!

With a lot of pups, leaving the crate open is asking for mess.  They have no need to hold it as they can easily move away from their bed.  Also, when teething begins, it's leaving them wide open to chewing on furniture..... and pups teethe for longer than many people realise.  So IMO it is better to get them used to being shut in the crate if you can as it prevents so may problems later. 

Having said that, I had  a friend who was having a nightmare getting her St Bernard housetrained.  If he was left in the crate he messed, if he was left in the kitchen he messed and chewed.  They tried a number of things with no success.  At te end of their tether they tried not confining him and giving him complete run of the house, against the advice of many.  His problems disappeared.  Odd.  I'd always recommend confining puupies to set them up for success and allowing more freedom as hey got older but it just goes to show you get exceptions to every rule.....  Dogs, unfortunately, haven't read the training manuals or dog forums like we have!
