I do think ALL Yorkies are just so YUMMY CUTE! I too fell into the 'teacup' phase - but b/c I had no clue. I was on the search for 2 little ones - a boy and a girl. I came upon TJ and Roxy - they were being sold as 'going to stay small' - I thought JACKPOT!!!!
Then I found YT - LEARNED SO MUCH HERE - Then I started to hope and pray they would grow

And they did. TJ is 7lbs and Roxy is 5 lbs. Although, they are probably a tiny, tad 'over weight' - but hey what can I say, they like to eat and it's winter

We can diet and excercise in the Spring. But they still would be in the 4.5 lb to 6.5 lb range.
They still have their share of 'health issues' - but that's BYB for ya!
