Why Emmy Looks Like Edward Norton in Fight Club

She just doesn't look down atthe ground when she is walking, dancing or running! Our family had a super time visiting with our friends and Emmy's big-girl friend Miss A yesterday, but a day cannot truly be complete without Em finding some hard or pointy object to slam her face into.
We have Em's 15 month check-up today, which means another appointment where we will have to explain a bruise on our daughter's face. Generally Em's pediatrician gives me a knowing and reassuring look, a la "I see this all the time  and don't worry, you are not a horrible parent", but I always wonder if she REALLY means it.
