I agree with the consensus, I believe that Lexxi sent her to you to ease your pain. It is a sign that she is at peace and wants you to make peace with her passing by sending you another baby to love and mother as well as you did her. She knows what a great mom you are and wanted another baby to experience your tender loving care.
The breeder is an angel as well to be willing to give you a new baby out of the kindness of her heart. What a wonderful person she is.
Good luck with your new little one. Oops almost forget to mention how beautiful she is.
