I just had a good conversation with the head of educational programs at one of our local art organizations. I was thinking about enrolling DD1 in one of their drawing camps for summer, which is advertised as very low-pressure and including spatial skills (which she has some issues with).
She was very nice and eager to make things work. To the point of saying that with enough notice, they hire interns to help kids one-on-one who need extra attention during the camps (obviously that's not the same as a para or adult aide, but still a pretty great option to have, IMO). It was really nice to feel like, okay, yeah, my kid is different but they're somewhat used to that and willing to do what they can to make it work so that she can have this experience. Actively do it, not just pay lip service to acceptance (which I feel is what happened with our camp last summer).
The director was really appreciative of me being upfront and willing to communicate about DD1's needs -- she said the toughest times are when a family knows their child has issues but gives no info and then they have to scramble to make things work once they figure it out.
I'm trying to book some summer camps for DD1 and figure out which ones are going to be the best fit. I hope the rest of the conversations I have are as welcoming and reassuring.
