Do we have a Mini Crash on our hands??

Today I took Lauren to the park with her bike and there are some small hills there well she got to going so fast she took her feet off the petals and then here comes the hill!!!!!!! And then she went over the top of the handle bars! Her helmet helped so she didnt hit to hard but it scared her and her face got a little scrape on it. It didnt bleed though. She cried for a second and then got back on it and went on about her way.
