Yes you can interact and join em as they play. You guys will have fun. Have you checked out romp N roll. Sound like he might enjoy the classes they offer
Yes, absolutely you will. Plenty of parents crawl into the jungle gum portion. Other spaces are quite open and designed for adult participation. In addition, there is a quiet room for anyone who needs a break--just ask at check-in. I'm a parent of a special needs child myself, and i never have any qualms about DPK.
I myself have done it.
