First Time Meeting

Hi all, I was wondering if anyone can give me advice on our first meeting, or how to handle the waiting for the meeting. We were matched with a 4 yr old boy and we are waiting to meet him. So far we are looking at 2 weeks b4 we can do this. I was wondering if anyone has been through this and can help. What can we expect from the meeting? What can we bring for him? We are very anxious and excited.
