Not sure what it is about stickers but our son is obsessed with   stickers!  The first thing he asks for is “Tickers, Momma, tickers, Daddy.”  He is pretty meticulous about the placement as well.  First he starts with a cheek then the left arm gets a ritualistic montage.  If you click on his picture you can see his pink sticker day (goes into his sister’s room and grabs whatever he can get his hands on).  You will also see in my latest photo post; pictures from the Cincinnati zoo during Quincey’s field trip.
