I'm so sorry I didn't see / respond to this sooner. There is actually a meetup group for some Maryland poly stuff (Of course now I can't find the link.) And if they're on Meetup, then I'm sure there's a Facebook group too.
It's ok. I'm reading your blurb about you. I have 2 kids who are austic as well. It's good to see some people in this community who just have kids. Haha. I'm 37f will be 38 in August and my Husband is 34. We are taking it slow but learning more everyday. The resources really help. Thanks .
