Look out for middle of the night puppies! My girls are notorious for it!
Lol.......I remember my first litter of puppies. Poor Cassie with a thermometer stuck up her b*** all the time. I had to quit doing that, it drove me nuts and her too! We were both a couple basket cases. I didnt sleep at all. Just like Mardelin said she got all glassy eyed, would get up, then lay down, Like Winston said, then stretch out. She certainly sounds like she is getting ready.
FOr fun IM gonna guess what time I think she will have them to entertain myself. hummmmmmmmmmmmmm hows about 1130pm tonight, your time.
Stay calm and enjoy. Its really an exciting time. Can be scarey but you will do fine.
