For sure get some NutriCal and a milk substitute. Also a good quality dry kibble -- Canidae is good -- get the puppy version of the kibble, it has more calories. Put a cup or so of the dry kibble into your blender and blend until it is more like a fine powder. Keep a dish of this ground kibble in the pen and available at all times to the puppy. Wet food isn't necessary even with a puppy this young. Keep fresh water in the pen at all times too. I've had moms decide to wean the puppies at 4 weeks, and they usually transition very well to the ground kibble and water. (having mom around for socializing and comfort is another issue altogether).
Get a fuzzy, soft stuffed animal to keep in the sleeping area with the puppy. Be sure the puppy is kept warm enough. I buy a yard of fleece cloth and cut it in half and use as little blankets in the bed so the puppy can snuggle in and stay warm. They wash easily and help hold the heat.
