Brooke, when I started reading your post, the first thing that entered my mind was:
1 - 2 people saw baby Tatum at the breeder and both wanted her.
2 - Tatum went to the best Mommy - Brooke.
3 - Other party was jelous, mad and totally stupid and waited for the first chance to pull an eigth grade stunt and tattle to the breeder trying to get Tatum "repossessed" so that person could get her.
But, whatever their reasoning, it's more than obvious from your posts and pics of your babies that you are an excellent Mommy. One look at you avatar says it all - your babies have "I am totally loved and spoiled" all over them.
You can't leave - you are the biggest reason I got Remington. I wanted another little girl to keep Roxy company, but every time I looked at Steddy's pics, I just melted. I decided a little boy wouldn't be so bad as long as I could keep his hair cut like Steddy's. So, you see, you have to stay so I can be sure I have Remy's hair right

. Besides, you are a big part of YT and we all love you here.
Tatum - get better quick, your mommy really needs you right now.
And, Brooke, you have every right to go ballistic on this person and I hope you get the chance.
