I can't answer all of your questions since I'm no expert, but I do remember when Rocco was around 3-4 months he would be down for the night around 10-11 and be up around 5:30 to go out to potty. And he did also have a lot of energy for playing - endless it seemed. But then he would just shut off like a lightbulb and sleep for a couple of hours a few times during the day.
I think it's a very good sign that Milo is so playful - he must be eating well to get all of that energy, and the giardia isn't getting the best of him.
