Really loves them. He likes flipping stuff over and spinning the wheels. He also runs his little cars up and down the hallway. He loves anything that spins - fans, a plastic windmill etc. He does like other toys (shape sorters, keys etc) and books too, but wheels are his first love.
Does this sound normal? Someone mentioned ASD and wheel obsessions and now I'm frightened. We were at a 1st birthday party and the other kids were climbing etc while DS played with the trucks. He does different stuff with the wheels (spins them, pushes the toys etc) and you can distract him from it. And he does get bored eventually. He will also bring his cars over to show me every once in a while.
