People, guard your knuckles. The baby is teething and your knuckle is her choice of chew things. I don't care how careful you think you are or how much smarter than a 4 month old you think you might be...you're not. She will slide in for the sneak attack looking all cute holding your fingers and sitting or standing up like a big girl, next thing you know she's got your finger in her mouth gnawing away on it. When you yelp with suprise she will laugh with her mouth full and shoot you a look that says "This is mine now and I'm gonna eat it!" Noses aren't very safe either when your are trying to nuzzle said baby.
The upside? Now everyone can see her hungry monster face without getting a view of her booby buffet!
