I scanned through a few of these and now that you probably have the willies....I had a friend who's son did that along with rocks and crayons and weird things. Then one day he stopped. Just like that. My little sister ate dog food all of the time she loved it not really the same I realize but I am just saying I think that kids sometimes just do weird things. Not always a medical reason. I would still go and ask the pediatrician though. Because it could be something like a deficiancy. I am not a paranoid parent but better to be safe than sorry. Right? Good luck!
