Hubster discovered this toy, a car that you can put together and take apart, online and knew that C had to own it. Our son loves all things related to vehicles. He has hundreds of cars, trucks and planes, and studies each and every one of them. He talks about the lights, paint colors, doors and windows. When we are driving, he points out cars that look like ours, Grandpa’s, or his aunt and uncles’. A fixation isn’t necessarily a bad thing. You can play it up and use it to help your child learn.
