Can you tell if the pup is nursing at all? If you know for sure it is nursing then when it is done it will sleep..if it's not getting milk the pup will cry alot. Also you need to make sure she is making the pup pee and poo..what I always do is I hold the pups bottom end up to the mom a couple times a day just to make sure.
You can also make her lay on her side and sit there and watch to make sure the pup is latched on and eating. If she's trying to curl up too tightly around him that it could prevent him from nursing..
