We celebrated my DD's 7th bday @ CRT breakfast last year....
I did tell the CM when I made the ADR that it was her birthday so they made a notation. They gave me the phone # to call in order to order the slipper dessert. I ordered it about 2 months prior to the trip.
The breakfast was absolutely magical! My 2 DD's and I went for a girls' only meal (DH was off in Epcot). We got a wonderful table overlooking Fantasyland

. The Princesses were very attentive and our server presented my DD with a birthday certificate signed by all the princesses
My favorite part was this... during the wishing ceremony, my DD closed her eyes and waved her wand and "wished" for something.... when she opened her eyes, she looked disappointed. I asked her what she'd wished for. She wanted a Sherbert Webkinz

I asked her if there was something ELSE she wanted as she'd been talking about nothing but the slipper dessert my younger DD got the year before @ 1900 Park Fare for her 4th bday.... she said "Oh yeah-the slipper!" She closed her eyes again and really concentrated.... at that very moment, our server appeared almost as though it were orchestrated perfectly and placed it in front of my DD.... when she opened her eyes-the slipper dessert was in front of her!

Oh how perfect it was!!!!!
She still talks about that "wish" all the time
I do hope that your DD has a magical day there as well!! Good luck getting the ADR you hope for!
