Rash/bumps?

Amanda
Hi all,
My little girl developed these spots about a week ago. I thought it was a reaction to new food at first, but they don't seem to be going away. We've only given her safe/familiar foods since then, just in case. 
There are about 15-20 spots all over her body (not on face, hands or feet), but mostly concentrated on her legs. Some of the spots are larger than others and some have raised bumps while some are just red spots. 
Aside from the spots, she doesn't seem to have any other symptoms and they don't seem to bother her. No vomiting, scratching, changes in eating/sleeping, trouble breathing, etc. There haven't been any changes we've made recently (same soaps, lotions, detergents, etc). Any ideas what it could be? Thanks in advance!
