Welcome to Yorkie Talk! Congrats on your little dude!! I am a newbie to this forum too
We got our little Teddy on Valentines day and I totally know what you are going through...we had him picked out weeks before he was ready to come home with us. Our breeder kept sending us updated pictures and it was great to see him grow! Your breeder is smart to keep him until he is big enough to go home with you. Once you get him you will be more in love then you are now. Your girls are going to love him! Wish you all the best!!
