Andrea, I'm so sorry to hear about your little boy.  I hope you get all the help and support that you can.
Regarding the BR, yes, it really can be done that quickly!  I didn't have to make an appointment, it was first come first served and they see 4 people a day.  I had a long wait, but that was because I got there an hour and a half before the court opened - I was determined to be seen!  Once they actually opened it was really quick and painless - I was in with the judge for less than 10 minutes.
Good luck to you, hubby and your little boy x
Yesterday is history, tomorrow is a mystery, today is the present - a gift to make the most of.
