I'm so glad that mommy and babies are doing ok. Did the vet give you any pain medicine for her? She may just be very sore. If she is eating then she will probably be fine, just make sure her sugar doesn't get too low. You might give her some nutrical or Karo every few hrs to be sure and it will help her appetite too. I had to give mine the nutrical after delivery because her sugar got very low even though she was eating. I would also be careful about letting the daddy around too much, most mommies don't like that very much.
Please post some pics when you get a chance and good luck with your new babies!
