welcome mmmmom! your dd deserves a great deal of credit as well as respect! She has come further then many other gymnasts will ever come...
I hear parents talk like that all of the time when their dd's are 8's, 7's, 6's and even 5's about higher levels... I would say it is not worth even over hearing - many of these parents don't understand how difficult it is to get to and then stay, and then move higher into these levels. Chances are there will be an injury along the way and reality will set in... or maybe it will get too hard and their dd's will quit - you just never know. Let them talk! They will figure it out sooner or later - on the other hand, for you, keep in mind there is some point when everyone COULD get to the same level.... kinda the point in gymnastics

. Everyone will have their own talents and differences and there is room to appreciate all

... it is nice to "meet" you and looking forward to your mnay years of wisdom in this sport - ingymmom
