Aw Jane this is so sad. I remember how bad I felt when I lost 3 of my bunnies within 3 months. But to have lost your girls in such a short space of time must be awful. Keep your chin up and take comfort in the fact that even though they were born under such dire conditions, you were able to give them so much TLC in their very short lives. So many other bunnies will never know how it feels to be loved so much.
