Down syndrome awareness month

There are many in the online Down syndrome community who blog, and there is this thing called 31 for 21. October is DS awareness month and bloggers write a post every day of the month (as you remember, DS is Trisomy 21). I may not do 31 posts, but I will write a bunch this month as I think about what it means to be an advocate for my son, how informative the online community has been, how it feels to organize an event for this month for my work, what I would say were I to give a presentation about being a "special needs mom" and more.  

But I leave you with this question, and I really am curious to know your answers:  what do you know now that you didn't before knowing Liam?
