Heather: I nearly spit when I read that. LOL You have to remember the parents and grandparents sizes and the greatgrandparents if you can find all that out. Willie, Matty's dad, is 3# but his parents as far as I can find out are around 5#. He was the runt of his litter, I don't remember how many there were, and the owners thot he wasn't going to make it and gave him to his present owner who nursed him to health. This lady raises 2 different types of bull dogs and didn't plan on getting a Yorkie so she didn't do any research or ask enough questions of the parents owners.
I was only a month old Yorkie owner when I bought Lady, I had done some research but not enough. I didn't ask, demand, the answers about Lady's history. I was just too excited. Pirogue was 8 weeks when I got him and I wanted a female that would be in her second heat by the time he was ready. I had been shopping but older females are few and far between so when I found her and she was 4 mos older than he, I grabbed her. I realized much later that the lady didn't answer my questions about Lady's background.
So what I'm saying is I don't think Matty has any choice but to be a bigger Yorkie, how big I don't know. I can assume that Lady's parents are about the same size as she is but they could both be 8#. From the looks of her Matty IS NOT going to be less than 5# and that is conservative.
If you know some of the sizes in your mom and dads background you can make a guess as to how big the babies will be when they are grown. If I were keeping Matty to sell she would be, in my opinion, the perfect size for a family with children. I copied out one of those weight charts and set up a file in Excel so I can keep track of her weight at what week. As of this past Wed. she was off the chart!! LOL It says she'll be over 6#. I do keep in mind that she is carrying a lot, a lot of baby fat and growing fast because she is the only one eating mama's rich milk. I think she might finish at her mom's weight, 6.2 before she got pg.
Now, Mr. Big and Lacijo, are 5th generation smalls. I'm not sure what that means in the weights of grandparents and greatgrandparents, but dad is 2 3/4# and mom is 3#, oh the other mom is 3# too. They are half siblings by their father. Lacijo is 3.3# and 7mo. I don't think she'll make 4#, but who knows? Mr. Big is 4mo and weighs 2.15. If he is going to stablize at his dad's weight it means he won't be getting any bigger just gaining weight. I couldn't get close to his dad, he was in with another female, but he has lots and lots of hair, so he looks bigger than he really is. Mr. Big's mom wasn't much bigger than he was the first time I saw him at 8 weeks and the breeder said he weighed 8oz. If you would like to see what their parents look like go to this site:

Rip is the father of both of them and Raisen is Lacijo's mom, Gracie is Mr. Big's mom. I can't remember what size Autumn's parents were but she weighed 1.7 when I got her at 10weeks, she weighs 5.6 now. Sylvia
