I need some serious help here! I made an appt for BBB for my DD7 next month. I've been sooo excited for this but apparently she is NOT!

We made a quick weekend trip for P&PP last month and when we walked by BBB at WOD, the FGIT offered to sprinkle DD with pixie dust and she said, "no thank you." What???? I showed her was was happening with the makeovers and she was appalled! So I showed her all the little girls throughout the evening who I could tell had been to BBB. Then I even went so far as to tell her that the only way a girl could go to BBB was if they were invited by a princess. The FGIT needed practice so the princesses picked out special little girls to help out, yada yada yada. I figured she'd come around, right?
WRONG! I used a personalized BBB invitation from the wonderful designers on the Creative Designs thread, and had it "mailed" to DD. When she opened it up, she looked like she wanted to cry! She absolutely does NOT want to go! What can I do? I just know she'll love it! But I think it's the idea of having her hair brushed - she hates brushing through tangles. That's the only thing I can think of. I'm at a loss right now and MY heart is broken. It may sound terrible but I really want this for ME as much as for her, ya know? Little baby growing up and all that jazz!
