Hi and welcome to yt
I just got a new baby for my aunt and all though she is very tiny 1.5 oz at 12 wks , the breeder did not say teacup when i talked with her, she used the word tiny, you just never know how big they will get, my 4 range from 3lbs to 7pds
you will love your baby no matter what the size, it just stinks that peole use that word for money
enjoy your baby and please post some pics
