I had a trick to add that really worked with our little Zoe. She joined us at about 81/2 weeks, (which was definitely too young for her and she was quite sick for a long time, so my fingers are crossed for you that all goes wonderfully). When we first got her we cut a snuggly throw (probably about twin-size, soft and plush, from Target or Walmart for about $10-12) into 6 baby blanket-sized mini-blankets. We started wrapping her up in them right away and kept them all over the house for convenience. They are VERY comforting to her since she was comforted in them from the very start. She quiets right down and quits shaking or looking scared any time we wrap her up--vet visits, cold, lonely, just in from a cold outside potty time, feeling sick, needing to calm down, friends over and she's nervous...everything. I also use them to snuggle up on and around her when she's sleeping and it's chilly. Plus, with so many, I can always throw all but one in the wash and she still has one to use.
Maybe this will help. Enjoy and good luck!
