4 year old DS is obsessed with leads, wires, pipes, anything that connects to something else. Anything he can plug in and charge. Says he wants to be an electrician. He is possibly autistic and on the pathway for diagnosis. He has a couple of different marble runs and electric circuit kits already. He doesn’t like “normal” toys and does very little imaginative play. Any suggestions? I’ve seen some tube toys that you can connect on Amazon and some magnetic tiles which I will get but wondered if anyone has any ideas?
