What is in your nose?

A little history, Harper is one who likes to pick her nose and sometimes eat it... I know it is gross.  We make a big deal about how gross it is and that she should not do it, she gets pretty embarassed.  Well, today she was messing with her nose and I thought she was just picking it.  She then became nervous and was trying to blow her nose.  I was helping her, then she said "did it come out"? I wasn't sure what she was talking about, she became a little more upset asking if "it" came out.  I then realized that she put something in her nose.  In the meantime she threw up all over the bathroom from "upset stomach".  Her nose then started to bleed a little, I could see something in there.  Finally, she blew it out....part of a Squinkie.  I think and hope this will be the only time she does that!
