Is lining up toys and banging them away typical for play? DD lines up toys and plays with them typical also. Eg shell line up her animals making sounds then bang them away or hide them under a pillow. She doesn't get upset when I left them.
She also lines up cars sat together t goer colours and then imitates them on the road saying beep beep. She also lines up crayons and then colours in. Often she fires crayons and cars I under couch
