Zoe is beautiful, but if you dont feel attached maybe you should give her back.  If I just "think" about Tinkerbell not being with me one day I have cried, so obviously she is not the right one for you no matter what her size is!!  When I got TInkerbell I knew almost nothing about Yorkies, she was 9oz at 6 weeks (I believe if not less)She was predicted at about 2lbs she is 3 1/2 and is tiny, but it doesn't matter cause I lover her no matter what her size is.
 
Good luck to you and Zoe, I hope Zoe finds a good home if you do give her back and if you should decide to keep her love her no matter what

  jmo!!!  
Oh yeah I dont hate you for that either, I think no one would
