Wow. I can't believe that you are just NOW asking these questions, when she's due very soon
Please search out a mentor that breeds toy breed dogs who will hopefully help you. In the meantime, read every single thing on this board, it's a wealth of information, not to mention people's real life experiences with whelping and raising tiny puppies. So many things can go wrong with a whelp with these dogs, and not having experience or knowledge on your side could very well have put your girl in jeopardy
Praying that all goes well
