Don't call me Pinhead

At my 6 month checkup, I weighed in at 13 lbs 3.6 oz, with a height of 25 1/4" and a 15 1/2" head circumference. I am a relatively small baby; I'm in the 25th percentile for weight, the 50th percentile for height, and am about 2nd percentile in head size! My Daddy has nicknamed me Pinhead! The doctor says that I am advanced in my skill development... maybe my small size helps!
