OMG!!! Thank God you didn't take her back there!

Please follow Donna's instructions to the letter! If she is having real runny poo you can add a little chicken baby food in with the KMR and feed it to her with a syringe too. That will put a little extra into the milk replacement and will stick with her better. If you do add the baby food you may not want to feed as much. The taste should be very appealing to her as well.
Make sure you stimulate her to go potty and make sure you are feeding her in the prone position. If she is laying on her back then she can aspirate.
You probably already knew this stuff but just in case I'm throwing it in.
Prayers are on the way for the little sweety and for you. Thank you for caring enough to keep on trying. It may not work but thank God your not giving up on her.

Keep us posted

edit: you posted at the same time I did. I'm so glad things are sounding a little better. Keep on doing what your doing and as she grows add the baby food into the milk mix. They love it and it's full of vitamins too.
