Bean likely isn't getting enough to eat. Puppies will cry a lot when they don't have enough milk, and it would cause him to be lethargic and not gain weight. Newborn puppies are extremely fragile, so any problem with them should be considered an emergency. You need to take him into a vet now. Best of luck.
