Welcome to YT! There are so many knowledgeable people here it's awesome. Georgie was 1lb when we got him. There are a few pieces of advice that I can give you:
1.) Keep nutrical or karo syrup on hand. Put a little on your finger for her to lick a couple times a day. Their blood sugar can drop and they become hypoglycemic.
2.) No jumping it's so hard I know but she is just so small so stairs are awesome to get up/down on the beds, couches etc....
3.) Any diarrhea or throwing up (sorry to be graphic) please take her to the vet. I never took my chances with Georgie he was to small for me to not get him checked and potentially treated right away if necessary. He is still to small but after 6 years you start to figure things out
Your little furbaby will bring you so much joy and smiles they are amazing!
