Yes we need more info here! lol. It is normal for a puppy to bark and cry at night. My puppy did. It is best (in my opinion) to have the pup sleep in the same room with you. Possibly in a crate close to the bed, so you can reach your hand down to let the pup know you are there. The pup could be crying to be let out to go potty too, as young pups certainly cannot hold it for long! You might have to take a few middle-of-the-night trips outside for potty time.
