Both had big heads as babies / toddlers ... in the 99th percentile. Now they are no longer "that big". The issue only comes up when I need to put a sweatshirt with a hoodie that does not have a zipper on DS3.9! lol Then I get reminded that his head is still a little bigger and he's the more gifted (at least it's our suspicion)

I used to be laughed at by my cousins and friends for having a big head (I'm otherwise pretty petite so the head was standing out! lol)
