My son Peter has a special internal homing device. He's always finding fuzz in strange places. Then he rolls it into a little ball, and pops it in his mouth!
Nine times out of ten I can tell he's got something in his mouth, and when I have him spit it out it's fuzz!
Now why he chooses to put fiber fill, carpet fuzz, yarn and random lint in his mouth I have no idea. He doesn't eat legos, but he finds unnameable crumbs and of course being nearly two, pops them in his mouth without further ado!
Viva la fuzz!
