Hi there and welcome to YT as you have already heard there is a ton of information on this site.
As far as the puppies that are comming congratulations and we look forward to baby pics as soon as they arrive.
You will find in the breeder section a wealth of information when you are expecting puppies, and things you might need to help you along. There is even a post about what to have in your whelping kit for the big day.
I am also expecting my first litter the first part of March, the 8th to be exact so it will be fun to see all the little ones
good luck and welcome to YT
