Body Orifices

Despite the title, the subject is pretty benign, but Lorelei keeps putting things up her nose and in her ears and, as always, in her mouth. I don't know if she started putting things in her ears because they hurt, or what, but she does it all the time - whatever she can find - usually crayons or chalk. And then lately it's been putting things up her nose. Last night she put two kernels of corn up her nose. Bob got the first one out pretty easily but she had to blow for a while before the second one came out (it was pretty far up there). When she finally blew it out, it went flying across the room. I was laughing so hard, I was crying, but seriously, how can I make her stop? I'm envisioning a trip to the ER...
