I have 2 daughters with Down's syndrome. My brother also has it. And I also would have had a cousin with it except my aunt did not keep the pregnancy. I'm wondering how common this is. I do not have any form of downs. I have been told it's not genetic but apparently for our family it is. My mom also told me that looking through family history it looks like there have been more. It's ALL from my dad's side of the family.

It genuinely is not genetic and not transferable through the DNA.
As I'm sure you know it is a replication of the 21st chromosome, meaning there are three instead of a pair. This is a fault in the replication and nothing to do with the genes.
As you are obviously aware, age is a factor and I wonder if this is what runs in your family, late births? Was the mother of the Down's children particularly older than the norm?
Aside from this I can only conclude it is a coincidence, out of the whole world, statistically speaking there had to be a family with an exceptionally high number of people with Down's somewhere, it just happened to be yours.
Let see my mom was about 32 or 33 I think. And my aunt was around the same age. As for me I am extremely young. My first daughter with Down's syndrome was born when I was 22(died at birth) My second daughter who also has Down's syndrome was born just 3 months ago. And I am 23 years old. It's also as if their muscle tone seems to be low but it's really not. My second daughter rolled tummy to back at 1 week old. Not by accident she has been doing it ever since. She rolled back to tummy at barely a month old. Again she has done it multiple times since then, so she has plenty of muscle to do it. My brother is the same way he has great muscles that just seem like low muscle mass. I am just baffled by all this I've tried to find any information about this happening before and I just can't seem to.
