Kristin,
I'm sorry to hear about your loss.  I think the way you talked your girls through their emotions and grief was wonderful.  It's such a hard thing to explain to begin with and then adding your own feelings on top...well, it's tough.  I love that you share your memories with them too.  It's important for you all to keep those memories and good feelings at the surface, especially right now, during this hard time.  It will help to get you through.  Prayers and best wishes for your family.
