Hello Breeders

My female Yorkie, Penelope is due to whelp any day now. I have set up a box for her in an area next to my bed. I've experienced helping a dog I had many years ago give birth. But its been a long time. I'm not a breeder, just a pet owner who's female got pregant from a visiting male yorkie. She is very small but my vet has been keeping a good eye on here and feels that everything will go well. She had an ultra-sound and the pups all look healthy.
I have prepared a kit to help in the whelping process. Is there anyting I am missing?
