Oh...I know you will miss your baby!! I'm sure she will be fine though...sort of like a sleep over! The breeder idea is a great one...I'm sure she will love having some time to spend with her again and I'm sure she will be in excellent hands!
The trial idea is really good too...that way Schatzie can see that it is o.k. and you will always return to get her.
You are a good mommy and Schatzie is lucky to have you!
