Parents having a hard time thinking of an appropriate birthday gift for a son or daughter may be wise to remember wheel appeal. Boys and girls adore toys that roll -- especially when they're riding on them.
A birthday toddler may be ready for his or her first tricycle. A few years later, he or she can graduate from three wheels to two (or four, if you count training wheels). In case a bicycle feels passé, consider roller skates, rollerblades or skateboards. Just don't forget the obligatory helmets and padding that should come with bikes and skates. You want your birthday child to have fun and also stay safe.
