As usual, she positions herself between me and the babies.
Evil was in the stall with Buttercup, who was, herself, in the first stages of labor and aggressively trying to steal the babies for herself. I had to get Husband to help me move her to another stall.
Having learned my lesson about leaving them to labor alone, I stayed with Buttercup (aka Butterball, Buddha, Big Bertha) until her babies were born. She had her standard chunky twins. They're almost identical. Hers came about 45 minutes apart, so there was no danger of neglecting one. I helped clear their heads from the sac anyway, just to be safe.
