Here is how weird I can get

I saw a 5 pound Yorkie this morning and I thought he was big compare to Bikini that is 3.6 pounds. Does it make that much of a big difference when adding a pound to a Yorkie. Mine looks so little compare to the 5 pound. I'm so afraid of her getting huge. She is 4 months at 3.6. I just think they are so cute when they are tiny!
I hope she won`t go in the 15 pounds.... but I guess I will love her anyway!
