What will the judge ask?

I am adopting my 2 step daughters who's biological mom is deceased and we go to court tomorrow. Since we are doing this ourselves we do not have an attorney and I have just been dealing with the assistant to the probate judge. She said the last time we talked that everything was finalized and tomorrow would just be a quick before the judge and pictures. 10-15 minutes max. But I am curious as to what the judge will ask me and my 2 step daughters? I've never been to court before and this is a huge deal so I am a little nervous and want to be well prepared. Any advice or previous experiences?
