Time for a bicycle?

While strolling through the clearance aisle at Wal-Mart, Rainey found this...a Hot Wheels helmet.  I had my back towards him and when I turned around he already had it on his head.  It says for a 5-yr-old but fit him just fine :)  A few minutes later, he grabbed my hand and walked me to the bicycle section.  Not really sure where he learned that he had to wear a helmet while riding, because we don't when we take them in the bicycle trailer.  I guess we better start.  Oma and Opa, better get out the Big Wheel out of the attic!
