I want to know!
I notice with Baby Girl that she puts EVERYTHING in her mouth and when it actually *is* something that is edible, she jams it in there.
Son did have an issue with eating non-food items when he was younger (he LOVED to eat paper) but he put less things in his mouth and when it was food, he was really good about putting in only the smallest pieces at a time.
So is this a boy vs girl thing? Or an autism vs neurologically "typical" thing? Or a first child vs second child thing?
Or just a coincidence???
