I was looking for pads that would work for my 2 year old son and my 3 1/2 year old daughter.  I didn't want to buy the cheesy ones that they make for little kids, especially since I couldn't find any that didn't come prepackaged with helmets (they already have new helmets).  I wanted pads because my 2 year old loves to ride his scooter and he's quite the daredevil!  So, before he left most of his skin on the pavement, I wanted to try to prevent this.
