I recall being taken shopping for Easter shoes at age 8, and feeling embarrassed to take my shoes off because of my bunions.
Get her feet fixed NOW. If you have insurance, you'll be amazed at how little it costs to do so. Also, it will save her an adulthood of foot problems secondary to the bunions, including hammertoes and capsulitis--not to mention pain.
In the meantime, crocs and clogs are good bunion disguisers.
