*sigh* Oh, dear ... this was not the news we were all so hoping for. It is never, ever easy to see such a thing and I am so sorry you (and your sweet little BouBou) had to go through it. Remember to be kind to yourself and for the next couple of days, it might be good to offer your little grieving Mommy a little goat's milk and kitten food mashed up together and gently warmed. Cool compresses alternated with warm ones might help to relieve the milk pressure while it dries up. Give your little girl lots and lots of love now as she will be wanting to "find" her babies ... keep her distracted as best you can and she will be ok in a week or so. My heart is with all the others in sharing your grief.
