Hi and welcome. Also congratulation on your new little fur-girl! She looks very, very young in that picture. How old will she be when you bring her home on the 22nd? As for food, there is nothing better than home cooked. You can make it up and freeze in advance. Also the wee-wee pads are a must when leaving a puppy at home, but not to crate them. Use an expen attached to the front of the wire crate. Tie the crate door open. Put a blanket over the crate to create a den-like area. Put the pad at the opposite end, attach the water to the side of the pen and leave a nylabone chew and a little puppy kong.
I'll attach a picture of how the expen and crate look. I took this just for posting since mine are older and don't need the expen for containment now.
