I managed to get the kitten to drink milk that I brought from Petco. After the feeding and cleaning, it settled down and quieted, bringing down the mamma's stress level, making it easier for her top lactate, and lay down with the baby.
No other kittens have been born yet, and with the mamma relaxing and seeming much better, I think it may be safe to say this is the only kitten being born. her belly swelling is already going down. My sister says she see's the baby now nursing from the mother regularly.
I've still unable to check the kitten's gender, but my sister has already named it Lucky, since it was lucky to be born inside a warm house, when it's freezing as hell outside. And, it was lucky to have been born from a very tough cookie mom.
I'll be posting pictures of the kitten later.
