Is my baby too fat??!!?

haha he is soo cute! I would never consider any baby fat, maybe chunky but arent they supposed to be? My son was 7.13 at birth and at 13 weeks is 18 lbs and the first thing I ever hear is "wow, look at those chunky thighs, he's HUGE!!" so I know how you feel! But I take it as a compliment that my baby is healthy and very well fed!
