Sometimes giving some carnation condensed milk, or vanilla ice cream can help a bitch continue when she is tired out, will start the contractions going again.
But in the end, it sounds like a good delivery. She has a big job to do, so give her plenty of delectable nourishment. I usually give either yogurt or cottage cheese, meat, eggs, and some kibble with every meal, at least for the first week or so. Then I might back off a little on the extras if the pups are all gaining wait and doing good.
If she has eaten all the placentas, expect some serious black yuck poo outside. She may not be hungry right away, but if she does seem to go off food, take her temperature and make sure she isn't running a fever.
It sounds like she is a good mother, and everything is going good.
I would send someone for a kitchen scale. Walmart sells them cheap. Weighing the puppies twice daily will tell you if any are in trouble and if the bitch is doing ok. I use different color rick-rack to tell them apart, and check them so that they are not too tight or too loose every time I weigh them.
