We just had our first litter 6 weeks ago and the BEST advise that I got was to stay calm, I felt I was as prepared as I was going to be,since it was so unexpected and KEEP the computer ON...
everytime I felt I needed to ask something I did and almost all the time someone answer me back which made me feel a WHOLE lot better.. also I had my Emergency Vet on speed dial in my cell phone and the regular vet on the house line...LOL
other than that, enjoy the experience and hope everything goes well for you and your girl..
hugs,
