My little under 3lbs baby was spayed a week ago..within 24 hours she was almost back to normal! like you, I was dreading it..but knew in the long run that it was the best thing for her..honestly..she will do so well and recover so fast you will be amazed! I know I was!!! My vet was brilliant..answered all my questions..and believe me..I went in with a LIST on a piece of paper!!! he totally put my mind at rest! she also had 7 baby teeth removed & a microchip. she has her stitches out next week...Goodluck! keep us updated on her progress...you will soon be posting on here telling us how well she did!
