My now 1-year-old has loved these vehicles from a very early age. When he was just a couple of months old, he liked watching us take the little green car and move it back and forth on the tray of his swing. Then when he was old enough to hold it, he loved to hold the little one and shake it (it rattles). He still zeroes in on that rattle. Now he likes to crawl around running the cars on the floor. And, he'll sit and just move the wheel on the top of the police car for what seems like a long time as he watches the colors change. Don't wait to open this one. It's useful from very early on.
