Most of our activities cost about a dollar of less. I get a lot of toys or materials second hand and for some that are new, they are usually cheap like washable paints, paper, puzzles etc. A lot of things we use are are already things that we have even when RC was not around.
To practice social skills, we also go to free activities for kids and go to the parks around the neighborhood. I love free, yay!
