Don't worry, my mum informs me I was like that too - I put *everything* in my mouth (hard to see why I'm such a fussy eater!) including dog poo, cigarette butts (yuuuuuck!), mud, etc. Oh, and I also used to go off at her if she picked all the egg shell out of my boiled/scrambled eggs... I ate the whole egg, shell and all, when she would let me.
Believe it or not, the eggshell freaked me out! LOL

My Mum used to tell me that I ate ****roaches when I was crawling around... ick!
