Stac,
So sorry to hear about your loss, I am sure you are completely worn out. Please know that we are all keeping you and your mare in our thoughts.
I hope that all goes well with Missy and that she does not have any ongoing problems from this difficult birth.
We are all so blessed when we have textbook deliveries. But it makes you realize that even in the best of facilities and the best conditions, thing can and will go wrong.
Keep us posted.
