My 7 year old daughter (No CF) just got one for Christmas. She actually is pretty good at it. She watches the older kids with theirs & has even watched competitions on tv so she has the general idea, but has to teach herself how to actually do it. She has very good balance which helps alot. Her balance got better after she enrolled in Karate & started rollerskating. Karate she doesnt currently do, but rollerskating we try to get to often.
