Jenn,
I am so sorry for the loss of Chloe's pups. Please know that you did everything possible for the survival of those pups and for that, you should be proud of yourself.
I, as well as others, have now learned something due to these unfortunate circumstances that will be very valuable in the future regarding preemie yorkie births.
Please give Chloe extra hugs and kisses from all of your friends here at yorkietalk.

Big hugs to you as well
