What happened to my sweet baby that used to just lay there?

Cal's not even crawling yet, but he manages to get into everything. Things I have pulled out of Callahan's mouth today:

• the rug
• one of my flip flops
• a sheet of return address labels
• a new debit card

He managed to get into all of these things while I WAS watching him... He never leaves my side but somehow gets into everything the second I turn my head. Let the baby proofing begin.
