time to think

We took our oldest up to visit her grandparents in PA the trip took a total of 10 hours round trip.  I had plenty of time to read through a friends adoption book and all their MAPP work.  Aghhh we're in for a long journey.  I read all the questions and we will be asked and I feel out of my league. I really hope that when we take the classes that they give us some help and knowledge because I am very lost.  I thought I knew a lot about kids and how to raise them but let me tell you I'm scared.
