Hello,
I am relatively new as well, the best thing for me for sure was finding these forums (these ladies are knowledgable and always helpful with advice) I have gained so much knowledge just researching past topics here!
The other really great resource has been the child care providers resource network "ccprn" (sorry I don't know how to link on my iPad). If you haven't joined yet you are going to be blown away by what they have to offer in terms of resources and education.

Good luck on your new enterprise.
