"Anyone ever notice how every kid on the Dis is extremely tall and talks extremely well?"
Well, when a question is about kids who are large or advanced for their age is it surprising that people answer who have kids who are tall and advanced?
For the record my girls are both very small but were articulate speakers.
My son was HUGE but not talkative. As a teen he towers over me and is still a man of very few words. He is an honors student but just not chatty.
There are many people here, on the Dis, with petite kids, huge kids, advanced kids, and kids with developmental delays. In our extended family we have kids with disabilities, kids with health issues, and kids who seem to lead golden lives.
