Wow 8 granddaughters all 4 and under! <img src="i/expressions/face-icon-small-happy.gif" border="0"> I bet that's just too cute when they all get together.
Well, I know that you won't really know what your new grandbaby needs until she is born, but you are smart to get prepared early. I hope that if she does need the bowel surgery, that it goes well, and she recovers quickly.
Everyone has given you great advice. I can only say that you should treat her just like the other precious little girls. Of course, you want to avoid unecessary germs, but you'd do that with any newborn. Your clinic will most likely be very patient with you, and will probably answer questions you didn't even know you had. Just take it one step at a time, and it will all fall into place. The most important thing to do is enjoy that baby.
Keep us posted.
