Sibling Angel Picture?

Jennifer Diaz of Florida sent us this picture of an orb. Could her son's sibling been with them? You decide...

"I took this picture of my parents playing tickle with my youngest son. This was November of 2005. I took it with our Kodak Digital camera. When I uploaded the pictures to my computer, I was in awe. There is plainly an orb and you can see the face in it. They always seem to appear at special occasions - mostly with my youngest son and I. I lost a baby girl at five months along in pregnancy, before having my oldest son nine years ago...and to me the face looks like a little child. I wonder if it could be her, Maritza?"
