They won't eat cake in case they make a mess. So tea /coffee and non messy cake /biscuits /small buns
I'd have a pad of paper and make notes . Sets the tone that it's a business like meeting. Keeps you focused and stops you talking too much . Unless you are a naturally quiet oerson -I tend to waffle when I'm nervous
You want them to do the talking . Ask them open ended questions . Make sure they are " decision critical " issues ie things that affect your decision whether the child is right for you
That might be developmental delays , contact or family background issues . Definitely ask about the legal situation
Don't ask about routines, food, toys ( unless the child has serious problem in one of these areas ) - you can meet with the FC later and find out all this stuff
Asking intelligent questions is the way to impress them, not telling them how great you are ( not suggesting you would, unless you work in sales or marketing ) .
Ask about the childs needs and what kind of family they think would be best for him .
Don't do a lot of emotional gushing about how hard your journey to adoption has been and how much you really really want this child and his birthday is the same as your granny's so it's meant to be . Blah blah blah . It's not the X factor , it's not therapy , it's a job interview .
