Sorry your 1st phone call didn't go to well, but it's good they are still meeting you.
Your 1st visit might take a long time if you ask lots of questions, that I am sure you have lots of.
My 1st visit went really well, I can't remember how long it took, but I had a long list of questions.
I am fostering not adopting, so a little bit of a difference, but they still do all the same checks.
I remember feeling so excited to getting started, but it was a scary time as well. Because it was some think I really wanted to do.
And now that I am approved and fostering it is just as I imagined it would be. ( so far....)
Hope your 1st visit goes well..
