DS will be 3.5 at Christmas and has started saying that he wants to ask Santa for a racetrack like the one on TV (I have no idea what commercial he is referring to). SO, what racetracks do your 3 YOs love? Is he too young for a hot wheels set? He has a Fisher Price Little People one and he loves the ramps on it...just not sure what else is out there and wanted to see what your LOs love!
